Question
Balls are thrown vertically upwards in such that the next ball is thrown when previous one is at the maximum height. If the maximum height is 5m number of balls thrown per minute will be :-
Options
A.40
B.50
C.60
D.120
Solution
hmax = 
⇒ u2 = = 12× 10 × 5
⇒ u2 = = 12× 10 × 5 u = 10 m/s
tH = 
= 1s so no. of balls in one min will be 60 x1 =60.
= 1s so no. of balls in one min will be 60 x1 =60.Create a free account to view solution
