Question

A race scooter is seen accelerating uniformly from 18m/s to 46m/s in 2s. determine the acceleration of the scooter and the distance travelled

Answer 1

Answer:

a=14 m/s^2

S=64 metres

Explanation:

From equation

a=(v-u)/t

a=(46-18)m/s/2 s

a=28/2 m/s^2

a=14 m/s^2

ii) From Equation

S=ut+1/2at^2

S=18*2+1/2*14*2*2[I have'nt shown Units cancellation to prevent Confusion]

S=36+28m

S=64 metres
