Question

an object starts moving from the rest with uniform acceleration and travels 20m in first 2sec what will be its velocity after 10sec from the start ​

Answer 1

Answer:

100

Explanation:

u=0 t=2s

S=ut+1/2(at^2)

Displacment in first 2sec

20=1/2(a *2^2)

a=10

Velocity after 10s

V=u+at

V=10*10=100m/s
