Question

A car travels at a uniform velocity of 60 metres second-1 for 10 seconds and it is brought to rest in 5 seconds calculate the the r e t a r r d a t i o n of the car and distance travelled in 15 seconds​

Answer 1

retardation of car is 48

distances in 15 sec is 65

Answer 2

u= 60m/s
v=0m/s
t=5
a=(v-u)/t
a=0-60/5
a= -12m/s^2
speed=distance/time
distance =speed X time
distance=60m/s X 15
= 900m
