Question

a ball is thrown upward vertically with a velocity of 55m/s calculate maximum height and total time taken​

Answer 1

Answer:

The equation is given as v  

2

−u  

2

=2as.

where,

v = final velocity,  

u = initial velocity,  

a = acceleration due to gravity, 10m/s  

2

,  

s = h = height traveled.

Therefore, we can find u with above info. In this case, v = 0 at the top of the path.

0−u  

2

=2×10×5=10m/s.

Hence, the initial velocity of the ball was 10 m/s.
