a child is swinging on swing, describe what happens to both the kinectic energy and potential enegry of the child as she swings up and down.
1 answer:
Answer:
The K.E is maximum when the child is at the vertical position and the P.E is maximum at the extreme deviated position from the vertical.
Explanation:
A child is swinging on swing up and down has both kinetic and potential energy. The total mechanical energy of the system is conserved throughout the system. At any instant the total mechanical energy is given by, E = K.E + P.E
The K.E is maximum when the child is at the vertical position. The P.E is maximum at the extreme deviated position from the vertical. And when K.E is maximum P.E becomes minimum and vice versa as per the law of conservation of energy.

Answer:
Part a)
distance = 112 miles
Part b)
current position = 112 miles from the position of town
Explanation:
Part a)
Since the distance marker is showing the distance between the town and the position of john at all time
so here we have
Part b)
Current position of John is given as
from the position of the town
Answer:
skateboard b
Explanation:
p=mv
skateboard a
p=(60kg)(1.5m/s)=90kg*m/s
skateboard b
p=(50kg)(2m/s)=100kg*m/s
