Asked by Alyssa
A 250 kg car starting from rest is pushed 30m. When the car reaches 30m, it’s traveling at a speed of 12m/s and it encounters 52N of friction. What is the acceleration of the car and what is the force of the push on the car?

During the period it is accelerating without friction, V = sqrt(2 a X)
Solve for acceleration a.
The pushing force during that time is
F = m a
You have not made it clear at what time you want to know the acceleration, Is it before or after friction is applied?
