Answer:
it take the ball to go up is 6 s
correct option is 6.0 s
Explanation:
given data
initial velocity u = 58.8 m/s
to find out
How long does it take the ball to go up
solution
we will apply here equation of motion that is
v = u + gt ..........................1
here u is initial velocity and v is final velocity that is 0 and t is time period and g is 9.8 m/s and ball going upward so we take g is -ve
so put here value in equation 1
v = u + gt
0 = 58.8 + (- 9.8) t
- 9.8 t = - 58.8
t = 6
so it take the ball to go up is 6 s
correct option is 6.0 s
