An object is projected upwards with a velocity of `100m//s`. It will strike the ground after (approximately)

A

10sec

B

20sec

C

15sec

D

5sec

Text Solution

Verified by Experts

The correct Answer is:
B
Time to reach ground `= (2u)/(g) = (2 xx 100)/(10) = 20sec`

An object is thrwon vertically upwards with a velocity of 60 m/s. After what time it strike the ground ? Use g=10m//s^(2) .

The velocity of a freely falling body when it strikes the ground is directly proportional to the square of the time taken by it to strike the ground. It takes 5 seconds to strike the ground, with a velocity of 10 m/sec. If it strikes the ground with the velocity of 40 m/sec, then for how long would it have travelled ?
