Question

A body is thrown vertically upwards with velocity of 98m/s . If g = 9.8 m /s^2 when will it reach its highest point and what will its max. Height .pls ans fast it is urgent

Answer 1

v= 98m/s
a = 9.8 m/s^2
u =0

v =u +at
or, 98= 0 +9.8t
or, t =10 s


v^2= u ^2 +2as
or, (98*98) =0 +2 (9.8)s
or, s = (98*98)/(2* 9.8)
or, s = 490 metres


Therefore the maximum height reached is 490 metres and it will reach its maximum height after 10 seconds.

Hope it helps
