Question

a body is released from rest from a height find its speed at t =1 second and T =2 second and t= 3 second​

Answer 1

Answer:i hope this helps!!

Explanation:

Answer 2

Answer: at t= 1s........v=10 m/s

at t=3 s ........v=20 m/s

at t=3s...........v=30 m/s

Explanation:

v=u+at

u=0 since released from rest

at t=1 s

v=0+(g×1)..........where g is acceleration due to gravity which is equal to 9.8 (approx. 10)

v= 0+10= 10 m/s

at t=2 s

v= 0+ (10×2)=20 m/s

at t=3 s

v= 0+ (10×3)= 30 m/s
