Answer:
1.87 s
Explanation:
Initial speed of throw = 9.20 m/s
Net vertical displacement = 0
The bowling pin would be in free fall i.e. a = 9.8 m/s²
Use the second equation of motion:
s = ut + 0.5at²
0 = (9.20)t-0.5(9.8)(t²)
9.20 = 4.9 t
⇒t = 1.87 s
Thus, the total time of flight, the time elapses before the bowling pin falls in juggler's hand is 1.87 s.
A juggler throws a bowling pin straight up with an initial speed, the time that elapses before the pin reaches the juggler's hands is 1.88 s.
Given:
Initial speed, u = 9.2 m/s
The time can be calculated from the second equation of motion. The second equation of motion provides a relation between height, initial speed, acceleration, and time respectively.
From the second equation of motion:
h = ut + at²
When the ball reaches the hands, the distance becomes zero. Therefore, the time is:
0 = 9.2t -0.5 × 9.8t²
9.8t = 18.4
t = 18.4÷ 9.8
t = 1.88 s
Hence, the time that elapses before the pin reaches the juggler's hands is 1.88 s.

At the beginning of a basketball game, a referee tosses the ball straight
up with a speed of 4.6 m/s. a player cannot touch the ball until after it reaches its maximum height and begins to fall down. what is the minimum time that a player must wait before touching the ball? s

t=4.6/9.81 ... about half a second
The speed of the stone when he releases the sling is equal to 9.95 m/s.
Given the following data:
To determine the speed of the stone when he releases the sling:
First of all, we would solve for the angular velocity of the stone by applying
the law of conservation of momentum.
Tension in the string = Centrifugal force of the stone
Angular velocity = 6.63 rad/s
Now, we can determine the speed of the stone when he releases the sling:
Speed, V = 9.95 m/s
