Question

a car travelling at a speed of 10 metre per second is brought to rest in 20 seconds by applying brakes calculate the acceleration and distance travelled during this time

Answer 1

u=initial velocity
v=final velocity
a=acceleration
s=distance travelled
t=time taken to travel the distance


u= 10 m/s
v= 0 m/s
t= 20 secs

a= v-u/t= -10/20= -0.5 m/s^2

s= -u^2/2*a

s= 100/1= 100 m

Answer 2

hope this may help you thanks byy
