Answer:
a toy car was on the floor in the play room until the child applied force by starting to race with it. it accelerated and proceeded to move at 5m/s east. it came to a stop when the bedpost applied force to it.
Answer:
Friction = 5 N
Explanation:
As we know that block is moving at constant speed
So the acceleration of the block is zero
So we will have

for net force to be zero
Force exerted on the object by external system must be counter balanced by the force of friction
So we have

so we have

Distance/ time = 100/5 = 20 km per hour
The average speed at 5hrs is 20 km per hour.
