If you stand next to a wall on a frictionless skateboard and push the wall with a force of 50 n , how hard does the wall push on you? express your answer to two significant figures and include the appropriate units.

50 N

Explanation:

Newton's Third Law, also known as the law of action-reaction tell us that the force exerted by object 1 upon object 2 is equal in magnitude and opposite in direction to the force exerted by object 2 upon object 1. So, if you exert a force on a wall, it exerts the same force on you in the opposite direction.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
