Question

vehicle does accelerates from 68 M per second to 60 M per second in 8 seconds calculate the disc acceleration and distance

Answer 1

initial velocity (u) = 68 m/s

final velocity (v) = 60 m/s

time taken (t) = 8 s

acceleration (a) = v-u/t

= 60 - 68 / 8

= -8/8

= -1 m/s^2.

distance (s) =

2 a s = v^2 - u^2

2 * -1 * s = 60^2 - 68^2

-2s = 3600 - 4624

s = -1024/ -2

s = 512.
