A car is travelling north at a constant speed of 20 m/s. A force is applied directly east on the car. The motion of the car will
be change in which of these ways? A) The speed of the car will increase. B) The speed of the car will decrease. C) The speed will increase, and the car will change the direction it is moving. D) The speed will remain the same, but the car will change the direction it is moving.
C) The speed will increase, and the car will change the direction it is moving.
Explanation:
The car is travelling north at constant speed. The force applied to the car is in the east direction, so it won't affect the speed in the north direction, but it will increase the speed in the east direction. Therefore, the net speed increases, and the car changes direction.
