Question

A body is thrown horizontally from a tower, 100 m high,
at t = 0 with a velocity 10 m/s. The velocity of the body
is directed at an angle 45° with the horizontal at a time
equal to (g = 10 m/s2)
a). 1 s
b). 2 s
c). 3 s
d). 4s​

Answer 1

Answer:

The horizontal component of velocity is constant as no horizontal acceleration is present. Hence, The velocity of the body is directed at an angle 45° with the horizontal at a time is 1 sec. (1) is correct option.
