Question

QUESTION 5 A ball is thrown up in the air with the initial velocity of 58.8 m/s upward. How long does it take the ball to go up? 6.0s 7.05 O 625 O5.05

Answer 1

it take the ball to go up is 6 s

correct option is 6.0 s

Step-by-step 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
