Question

A vehicle moving with a speed of hundred metre per second on applying brake it will stop after 10 seconds.sign acceleration

Answer 1

Answer:

v=0m/s

u=100m/s

t=10 sec

a=v-u/t

a=-10m/s²

Answer 2

Answer:

initial velocity (u) = 100 m/s

final velocity (v) = 0m/s

time (t) = 10 sec

using the formula ,

a = v-u/t

= 0 - 100 / 10

= -100/10

its negative so it causes retardation

= -10 m/s² ans

hope it helps

thanks
