1) A 2.0 kg toy car travelling along a smooth horizontal surface experiences a horizontal force Fas shown in the picture to the left. Assuming the rightward direction to be positive and if the car has an initial velocity of 60.0m/s to the right, calculate the velocity of the car after the first 10.0s of motion. (Force is in Newtons and time in seconds). (Hint: Use impulse-momentum theorem) F 5.0 10 0 -10
