Question

A body moving with an initial velocity of 30ms~1 acceleration uniformly at the rate of 10ms~2until it attain a velocity of 50ms~1 what is the distance coverd during the period

Answer 1

Answer:

u= 30m/s

v= 50m/s

a= 10 m/s²

v²= u²+2as

(50)²=(30)²+2(10)s

2500=900+ 20s

2500-900=20s

1600=20s

∴ s= 80m
