hello I have a few questions :confused:
thank you!:)

1) Calculate the force you exert as you stand on the floor assuming you weigh 180 lb. (1 lb = 0.454 kg).

2)A dragster starts with zero velocity and completes a 402.1 m (0.2513 mile) run in 4.910 s. If the car had a constant acceleration, what would be its acceleration and final velocity?
m/s2 =?
m/s=?

3)After a day of testing race cars, you decide to take your own 1460 kg car onto the test track. While moving down the track at 10.0 m/s, you uniformly accelerate to 32.0 m/s in 10 s. What is the average net force that you have applied to the car during the 10 s interval?
N=?
n is newtons

4)A race car has a mass of 718 kg. It starts from rest and travels 44.0 m in 3.0 s. The car is uniformly accelerated during the entire time. What net force is exerted on it?
N=?

5)Your mass is 80 kg. You stand on a bathroom scale in an elevator on Earth.

(a) What force would the scale exert when the elevator moves up at a constant speed?
N=?
(b) What force would the scale exert when it slows at 2.2 m/s2 while moving upward?
N=?
(c) What force would the scale exert when it speeds up at 2.2 m/s2 wile moving downward?
N=?
(d) What force would the scale exert when it moves downward at a constant speed?
N=?
(e) What force would the scale exert when it slows to a stop at a constant magnitude of acceleration?



6) A boy exerts a 38 N horizontal force as he pulls a 54 N sled across a cement sidewalk at constant speed. What is the coefficient of kinetic friction between the sidewalk and the metal sled runners? Ignore air resistance.



thank you for the help everyone!

Hi, Have you tried some of these questions? How far have you got?

I'm happy to help you understand, but I will not do your homework for you, because that won't help you to learn.

Let me know how you are getting on and I will do my best to help you :)

Most of these questions ask for you to apply SUVAT equations and F = ma, which you should have been taught about.
Let me know if you get stuck!
