A tennis ball was thrown straight up with initial velocity of 22.5 m/s. How high does the ball rise
1 answer:
Answer:
Explanation:
<u>Vertical Launch Upwards</u>
In a vertical launch upwards, an object is launched vertically up without taking into consideration friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:
The tennis ball was thrown straight up with a speed of v0=22.5 m/s. The acceleration of gravity is g=9.81\ m/s^2, thus:

Answer:
rev/s
Explanation:
= mass attached to each hand = 5 kg
= initial distance of masses in each hand = 1 m
= final distance of masses in each hand = 0.1 m
= moment of inertia of body = 5 kgm²
= initial total moment of inertia =
= initial angular velocity = 1 rev/s
= final total moment of inertia =
= final angular velocity = ?
Using conservation of angular momentum
rev/s
Answer:
Explanation:
Time period is the reciprocal of frequency
T = 1/F
F = 1/T
but angular frequency w = 2πF
F = w/2π
