Answer:
<h2>245 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>245 J</h3>
Hope this helps you
Answer:
Explanation:
When physical pendulum is a system of rod and sphere then we will have
so we will have
so we will have
since mass of ball is much higher than the mass of rod
so we have
now when we use the rod as physical pendulum then we have
M = 0
so we have
so its time period is given as
