Answer:
The average power is calculated as 735.0 W
Solution:
As per the question:
Total mass, M = 1200 kg
Counter mass of the elevator, m = 950
Distance traveled by the elevator, d = 54 m
Time taken, t = 3 min = 180 s
Now,
To calculate the average power:
First, we find the force needed for lifting the weight:
Force, F = (M - m)g =
Now, the work done by this force:
W = Fd =
Average power is given as:
Answer:
Explanation:
Given
time of contact between bat and ball is
suppose u is the incoming velocity and v is the final velocity after collision
Impulse exerted is given by change in momentum of the particle.
Initial momentum
Final momentum
Change in momentum
Impulse
