The question is incomplete, the complete question is;
A car is moving at a constant speed of 3 m/s when a force of 25N is acting on it. What will happen if the force is changed to 35N?
The car will move at a constant speed of 13 m/s
The speed of the car will not change.
The speed of the car will increase.
The speed of the car will decrease to 1 m/s
Answer:
The speed of the car will increase.
Step-by-step explanation:
When a the force acting on an object moving at constant velocity is changed, its velocity changes accordingly.
The question said that the car was moving at a constant velocity of 3m/s when a 25 N force is applied, then the car must move faster than 3 m/s when a 35 N force is applied since the 35N force is greater than the 25 N force.
Hence the answer above.
