Answer:
122.45 meters
Explanation:
G.P.E is m*g*h
The mass is 80 kg and gravity is 9.8 m/s². The G.P.E is 96000 J
Plug those in to the equation
96000=80*9.8*h
Multiply 80 and 9.8 to get 784
96000=784h
Divide by 784 on both sides to get h=122.45 meters
Hope this helps
Answer:
A. 4.47 m/s
Explanation:
As the ball oscillates, it mechanical energy, aka the total kinetic and elastics energy stays the same. For the ball to be at maximum speed, its elastic energy i 0 and vice versa. When the ball is at rest, its kinetic energy is 0 and its elastic energy is at maximum at 50 cm, or 0.5 m
1500 g = 1.5 kg
B. Cross training
when you're cross training, you are training in multiple different skills at once
