Question

BODY PROJECTED VERTICALLY UP FROM A TOWER
A body is thrown vertically up from the top of a tower with a velocity of 2 mls. Its velo
two seconds
2) 21.6 m/s
3) 20.6 m/s
4) 23.6 m/s​

Answer 1

Answer:

2) 21.6 m/s

Explanation:

given,

a ball is thrown vertically upward

the initial velocity of body(u) = 2 m/s

given time to find velocity (t) = 2s

gravitational acceleration(g) = -9.8 m/s

v = u + gt

v = 2 + 9.8(2)

v = 2 + 19.6

v = 21.6

so,

Its velocity in two seconds

= 21.6 m/s
