Question

Moving with uniform acceleration, a body covers 150m during 10sec so that it covers 24m
during the tenth second. Find the initial velocity and acceleration of the body

Answer 1

Answer:

a=1.8m/s^2            u=6m/s

Explanation:

Symbols used:

u= initial velocity      v= final velocity        a= acceleration        t= time

t=10s          avg. velocity= 150/10= 15m/s               v= 24m/s

for constant acceleration avg velocity= (v+u)/2

(24+u)/2= 15

24+u= 15(2)

24+u= 30

u= 30-24

u= 6m/s

a = (v-u)/t

  =(24-6)/10

  =18/10

  =1.8m/s^2
