Answer:
Efficiency can be increase by using rollers in conjunction with the inclined plane. Wedge. The wedge is an adaptation of the inclined plane. It can be used to raise a heavy load over a short distance or to split a log
Gravitational Potential energy is the energy stored with regard to position.
the equation for potential energy is as follows
P.E = mass x gravitational acceleration x height from the ground
gravitational acceleration - 9.8 ms⁻²
substituting the values in the equation
P.E = 125 kg x 9.8 ms⁻² x 1500 m
P.E = 1 837 500 J
therefore the potential energy of the diver at 1500 m high is 1 837 kJ
Answer: Negative punishment includes taking away a certain reinforcing item after the undesired behavior happens in order to decrease future responses. Positive punishment involves adding an aversive consequence after an undesired behavior is emitted to decrease future responses.

Conservation of momentum so the total initial momentum in the system is equal to the total final momentum in the system. You must remember that if an object is travelling in the negative direction, you must put a negative sign for the velocity.
mv + mv = mv
plug in all the numbers
(0.0323)(4.50) + (0.078)(-1.12) = (0.0323 + 0.078)Vf
multiply everything together
0.14535 - 0.08736 = 0.1103Vf
simplify
0.05799 = 0.1103Vf
isolate for vf
Vf = 0.5257m/s east
