Answer:
Explanation:
Momentum is the mass of a moving body times its velocity. It can be transferred from one object to another
Answer:
F = 145 N
Explanation:
Given that,
Force applied by Jeff is 85 N and the force applied by Chris is 60 N. Both forces are acting in the same direction to push a rock up a hill. It means that net force is equal to the sum of these two forces.
So,
Net force on the rock = 85 N + 60 N
= 145 N
Hence, the net force on the rock is 145 N.
Answer:
563403.5 J
Explanation:
= mass of the skydiver = 64 kg
= Altitude of the airplane = 0.90 km = 900 m
= speed at the time of landing = 5.8 m/s
Gravitational potential energy of the skydiver at the airplane is given as
Kinetic energy of the skydiver at the time of landing is given as
= Energy dissipated by air resistance
Energy dissipated by air resistance during the jump is given as
