Given
A juggler throws balls vertically upward
Time = 1 sec
He throws balls at a speed such that there are 3 balls always in air
To Find
Initial Velocity of each ball
Solution
● v = u + gt
● So here the time would be 3 seconds and the ball thrown first would reach the maximum height then the time would be 3/2, which is 1.5 sec
✭ Initial Velocity of the balls :
→ v = u + gt
v = 0 m/s
u = ?
g = -10 m/s²
t = 1.5 sec
→ 0 = u + (-10) × 1.5
→ -u = -15
→ Initial Velocity = 15 m/s
∴ The initial Velocity of the balls is 15 m/s, i.e Option b
