Question

A motorcyclist move with a speed of 5 metre per second is subjected to an acceleration of 0.2 metre per second square calculate the speed of the motor cycle after 10 seconds and distance travel in this time

Answer 1

initial velocity , u = 5

acceleration ,a = 0.2

time required, t = 10 s

final velocity, v =?

distance travelled, s = ?

we know,

v= u+ at = (5 + 0.2 x 10) = 7

s = ut + 1/2 at^2 = 60
