TBAT Physics Special Test 3

A 4.0 kg block on a smooth plane inclined at 30° is joined by a light string over a frictionless pulley to a 2.0 kg block hanging freely, as shown. The system is released from rest. What is the magnitude of the acceleration of the 4.0 kg block?

A bus travelling at a steady 12 m/s passes a car that is at rest. At that instant the car starts from rest with a constant acceleration of 2.0 m/$s^2 in the same direction$. How far has the car travelled when it draws level with the bus?
