You can calculate potential energy by:
U = m.g.h
Where, U = potential energy
m = mass
g = acceleration due to gravity
h = height
Hope this helps!
My very eager mother just served us nine pizzas
Acceleration is F/M so the answer would be 12m/s^2
Answer:
1. The lowest stratum of the atmosphere
troposphere
2. Most of the earth's ozone is located in the
stratosphere
3. Earth coldest temperature occur in the
mesosphere
Explanation:
Momentum = (mass) x (speed)
Original momentum = (700 kg) x (30 m/s) = 21,000 kg-m/s
Final momentum = (700 kg) x (15 m/s) = 10,500 kg-m/s
Change in momentum = - 10,500 kg-m/s .
