Question

28. A body is thrown vertically upwards with an initial velocity of 19.6 m/s. If g = -9.8 m/s2, Calculate
following:
(ii) After how much time will it come back to the ground?​

Answer 1

Answer:

Here,

u=19.6m/s

t=5s

a=−g=−9.8m/s

2

v=?

Using v=u+at

We gaet,

v=19.6−(9.8×5)=−29.4m/s
