A 0.56 kg model rocket produces 53 newtons of upward thrust as it shoots upward off the launch pad. With what acceleration meters per second-squared does the rocket launch?
resultant force = thrust – weight
acceleration = resultant force (newtons, N) divided by mass (kilograms, kg).
Acceleration = resultant force divided by mass
53N/0.56
=94.64 approximately 95
= 95m/s^2
This means that, every second, the speed of the rocket increases by 95m/s2
the S.I unit of Acceleration is meter per second square.
The acceleration in meters per second squared that the rocket launch is 94.64m/s²
According to Newton's second law, the formula for calculating the force acting on a body is expressed as;
F = ma
F is the applied force
m is the mass of the rocket
a is the acceleration of the rocket
Given the following parameters
Mass = 0.56kg
Force = 53N
Substitute the given parameters into the formula as shown:
F = ma
a = F/m
a = 53/0.56
a = 94.64m/s²
Hence the acceleration in meters per second-squared that the rocket launch is 94.64m/s²

Question: If you are traveling by train and the trip is 125 miles and takes 2 hours winding through the mountains, a) whats average speed? b) how would this be different if the train in each of the following situations- Train at rest, Train traveling at constant speed in a straight line, and the Train with a braking force (the train in the middle of coming to a stop)
PLEASE ANSWER ALL ASAP
Answer:
Average speed 62.5 miles an hour. If the train was traveling at a constant speed in a straight line it would be much faster on getting to its destination

Find the displacement of the object moving at v= -2 m/s for t=5s
Answer:
d = - 10 [m]
Explanation:
We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.
[tex]v = d/t[/tex]
where:
v = velocity = 2 [m/s]
d = displacement [m]
t = time = 5 [s]
Now replacing:
[tex]d=-5*2\\d=-10[m][/tex]

A bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?
Answer:
200 N
Explanation:
There is only two needed factors in play here; the mass and acceleration
According to Newton's 2nd Law: F = m*a
Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2
Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons
Which of these waves travel the fastest?
- sound waves in air
- sound waves in water
- light waves in water
-light waves in vacuum
Answer:
light waves in vacuum
Explanation:
light travels faster than sound, and light is not affected by the air pressure, therefore it would still move at regular speed, thus being the fastest example

How large is the Milky Way Galaxy? A. It is the largest galaxy ever observed. B. It takes up over half of the known universe. C. It cannot be measured or compared. D. It is very small when compared to the universe
Answer:
D. It is very small when compared to the universe
Explanation:
The Milky Way can be regarded galaxy which has Solar System in it. Milky way gives the description of appearance of galaxy from Earth, it is a hazy band of light that's been formed from the stars which can be visualized in the sky during the night, though it cannot be sorted by mere human eyes. Milky Way has existed for about 13.51 billion years with the radius of 52,850 light years. the Number of stars in milky way is about 100-400 billion. It should be noted that themilky way galaxy is a very large galaxy but It is very small when compared to the universe

You are pushing a box toward your friend with a force of 15 N, and your friend is pushing the box toward you with a force of 30 N. What is the net force? What direction will the box move (toward you or toward your friend)?
Answer:
A. Net force is 15 N.
B. The answer is given below.
Explanation:
The following data were obtained from the question:
Force applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 NForce applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 N
Net force (Fₙ) =?
A. Determination of the net force.
Force applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 N
Net force (Fₙ) =?
Fₙ = Fբ – Fᵧ
Fₙ = 30 – 15
Fₙ = 15 N
Thus, the net force acting on the box is 15 N.
B. From the question given above, we can conclude that the box will move towards you because the force applied by your friend is greater than yours.
