Question

a ball thrown vertically upward with speed of 9.6 metre per second from the top of a tower return to the earth in 6 seconds find the height of Tower​

Answer 1

Answer:

58.8m. The ball has travelled negative/downward distance so we have to take the height negative. So, -h = -58.8m So, h = 58.8m.

Answer 2

58.8m is the Height of the Tower.

Given:

the ball is thrown vertically upward with a speed of 9.6 meters per second from the top of a tower and returns to the earth in 6 seconds.

To find:

to find the height of the Tower​.

Explanation:

The ball has traveled a negative/downward distance so we have to take the height negative.

since, -h = -58.8m

           h = 58.8m.

           u = 1 9.6 m/sec

           t = 6sec

           g = 9.8 m/sec^2

           V = 0 m/sec

Since, h = ut - 1/2 gt^2

Hence, h = 19.6(6) - 1/2 (9.8) (6)^2

               = 117.6 - 1/2 x 9.8 x 86

               = 117.6 - 176.4

               = -58.8

               = -58.8m

Hence, the height of the Tower = -58.8m.
