A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate (i) the maximum height to which it rises (ii) the total time it takes to return to the surface of the earth.

Text Solution

Verified by Experts

`V^(2) - u^(2) = 2gs`
`0^(2) - (9.8)^(2) = 2 xx (-9.8) xx 5 `
S = 122.5 M
(b) V = u + at
0 = 49 + (-9.8) f
t = 5 sec
Total time = 5+5 = 10 sec
