Answer:
Explanation:
Assuming motion of equation of SHM as
where,
t=time
thus velocity at any Point x is given by
when speed is 50 % of its maximum value
(b)When Potential Energy is 50 % of total energy
Total Energy
potential energy at any x is given by
Answer:
x = 16 [m]
Explanation:
This problem can be solved using the following equation of kinematics.
where:
Vf = final velocity [m/s]
Vo = initial velocity = 5 [m/s]
a = acceleration = 3 [m/s²]
t = time = 2 [s]
Now we can find the displacement using the following equation of kinematics.
