A juggler throws balls into air. He throws one when ever the previous one is at its highest point. If he throws n balls each second, the height to which each ball will rise is

A

` 5m`

B

` 3,75 m`

C

` 2.50 m`

D

` 1.25 m`

Text Solution

Verified by Experts

The correct Answer is:
A
Time of ascent=`1 rArr (u)/(g) =rArr u=10 msd^(-1)`
Maximum height attained `=u^(2)/(2g)=(10^(2))/(2xx10) =5 `.

In quick succession, a large number of balls are thrown up vertically in such a way that the next ball is thrown up when the previous ball is at the maximum height. If the maximum height is 5 m , then find the number of the balls thrown up per second (g=10 m s^(-2)).

Two rings are suspended from the points A and B on the ceiling of a room with the help of strings of length 1.2 m each as shown. The points A and B are separated from each other by a distance AB = 1.2 m. A boy standing on the floor throws a small ball so that it passes through the two rings whose diameter is slightly greater than the ball. At the moment when the boy throws the ball, his hand is at a height of 1.0 m above the floor. A stop watch which is switched on at the moment of throwing the ball reads 0.2 s when the ball passes through the first ring and 0.6 s when it passes through the second ring. The maximum height attained by the ball above the floor is:
