Homework Statement
a) 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?
b) As a baseball is being caught, its speed goes from 31.0 m/s to 0.0 m/s in about 0.0050 s.
(First I found out that the baseball's acceleration was -6200).
What are the magnitude and direction of the force acting on it?
What are the magnitude and direction of the force acting on the player who caught it
Homework Equations
a = change in velocity / change in time
F=ma
a = net force / mass
The Attempt at a Solution
a) i used the constant acceleration formula to find "a", then plugged it into the net force formula. my answer was wrong.
b) i have absolutely no idea what force is 'acting' on it, or how to approach the solution to the next two requirements. i simply am not a physics person. any or all help dearly appreciated. thank you
