Question

find the acceleration of a truck which is initially moving with the speed of 40 kilometre per hour and then comes to rest in 5 seconds

Answer 1

Initial velocity =40km/hr=>40x5/18=>11.11m/s

Final velocity =0km/hr=>0m/s

Time taken=5 sec

WKT:

V=u + at (or) a=(v-u) /T

a=0-40/5

a= - 40/5

a= - 8m/s^2...
