Hey there
how are u..................................................
No, because the energy is the capacity for performing work. Gravity is the force that draws everything to the earth's center.
Answer:
Explanation:
Given
mass of tree stump is 
mass bullet is 
velocity of bullet is 
Conserving momentum for bullet and tree stump
Initial Momentum 
Suppose 
is the velocity of the system
Final Momentum 
Initial momentum =Final Momentum
Find the average speed and the average velocity.
Average speed = distance / time
distance = 10 x 8000 m = 80,000 m
time = 20 min * 60 s/min = 1200 s
Average speed = 80,000 m / 1200 s = 66.67 m/s
Average velocity = displacement / time
Given that the race car made complete circles the final poin is the same initial point, then its displacement is zero and the average velocity is zero too.
