Question

01. A body is thrown horizontally from the top of
a tower of 5m height. It touches the ground at
a distance of 10m from the foot of the tower.
Then initial velocity of the body is
(g=10ms)
1) 2.5 ms
3) 10 ms
2) 5 ms
4) 20 ms?​

Answer 1

Answer:

please mark me as brani list

Explanation:

Height of the tower H=5 m

Time of flight T=

g

2H

=

10

2×5

=1 s

Range of projectile is R=10 m

Initial velocity of projectile u=

T

R

=

1

10

=10 m/s
