B. Equal distances are covered in equal intervals of time
2.
A body moving along a straight line with uniform acceleration has velocities of 10 m/s and 20 m/s at points A and B respectively. The velocity of the body at the midpoint of A and B is:
A car starts from rest and accelerates uniformly for 10 seconds to a velocity of 20 m/s. It then moves with uniform velocity for 20 seconds and finally comes to rest in 5 seconds under uniform retardation. The total distance covered by the car is:
