40 N. If you’re using F=MA MxA would be 10x4 which would get you 40 N

Answer:

Below

Explanation:

All we need to do for this question is to plug in our values and solve!

      Force = mass x acceleration

      Force = 10 kg x 4 m/s^2

     Force = 40 Newtons or 40 N

If your teacher requires you to round to sig figs it would be :

    F = 4 x 10^1 N

Hope this helps!

You and your friends are driving down the road. Your car breaks down. You have to use a 1,210 N force to push the car 201 m to t
Katyanochek1 [597]

Answer:

2.43\cdot 10^5 J

Explanation:

Since the force applied is parallel to the displacement of the car, the work done on the car is simply given by:

W=Fd

where

F = 1210 N is the force applied on the car

d = 201 m is the displacement of the car

Substituting numbers into the equation, we find:

W=(1210 N)(201 m)=2.43\cdot 10^5 J

how long does it take an acorn to hit the ground after dropping from the branch of a tree 12.5 m high?
Grace [21]
The right formula to use is: T^2= 2d/g
where T= time taken
d = 12.5m
g = is a constant and is equal to 9.8m/s
therefore, T^2 = 2*12.5/9.8 
Using the values above, the time taken for the acorn to reach the ground is 1.59 second
T = 1.59 S
