A racing car starts from rest and reaches a final speed v in a
time t. If the acceleration of the car is constant during this
time, which of the following statements must be true? (a) The
car travels a distance vt. (b) The average speed of the car is
v/2. (c) The acceleration of the car is v/t. (d) The velocity of
the car remains constant. (e) None of these.

Step 1

a)

The car travelled distance is equal to the average speed times of time that is vavgt but not equal to vt

Therefore, given statement is false.

Step 2

b)

The average speed of the car is,

Step 3

Therefore the average speed of the car is v/2

Therefore ...
