Question

A car is traveling at 15 m/s. If brakes are applied so as to produce uniform acceleration of-5 m/s. calculate the time taken by it to stop?​

Answer 1

Answer:

Correct option is

D

225 m

Initial velocity or speed u=15m/s

The acceleration a=−0.5m/s

2

When vehicle stops its final velocity becomes zero v=0

By applying equation of motion

v

2

=u

2

+2aS

0=225−2×0.5S

S=

2×0.5

225

=225m

Answer 2

Answer:

Answer is 225
