Question

A car and a bus starts moving from the same position.The car movers at a uniform velocity of 20ms-1 whereas the bus moves at an acceleration of 2ms-2 starting from rest. When will the bus catch the car​

Answer 1

Answer:

The bus will catch the car 20 seconds after the start of its motion.

Explanation:

Velocity of the car = 20 m/s

Acceleration of the bus starting from rest = 2 m/$s^{2}$

When the bus catches the car, the relative displacement between the two is zero.

=> Displacement of car =  Displacement of the bus

=>  $20t = \frac{2}{2} t^{2}$

=> t = 20 seconds
