Question

Sohan is playing with a ball. If he throws the ball in vertically upward direction with a velocity of 10 m/s, find the maximum height reached by the ball and time taken by it to attain the maximum height. Please answer fast i have exam tmmrw

Answer 1

Hope it is correct................

Answer 2

Explanation:

HLW MATE HERE IS YOUR CORRECT ANSWER...

Initial velocity of the ball in upward direction (u) = 10 m/s

Final velocity at highest point (v) = 0 m/s

Acceleration due to gravity = - 10 m/s^2

Let the maximum height attained is H.

Now, using the third equation of motion:

$v^{2} = u ^{2} + 2ah \\ 0 ^{2} = 10^{2} - 2 \times 10 \times h \\ h = 100 \div 20$

H = 5 m

Hence, the maximum height attained by the ball is 5 meters.

Let the time taken be t

v = u + at

$t = 10 \div 10$

t = 1 seconds

I HOPE IT HELPS U A LOT...
