Kinematics
A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine par…
Kinetic Energy and Work-Energy Theorem
In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the d…

Question

This is energy efficiency and the impulse momentum theorem. Can someone please show me how to compute this? With explanation and illustration/diagram please? Thank you.

A.) An electric bike with the power rating of 350 W does 3.5 x 104 J of work to move around a subdivision for 7 minutes. Calculate the following:

a) the power output of the e-bike

b) the percent efficiency (compute first the energy input)

c) illustrate the energy flow diagram for the e-bike.

 

B.) Patrick is good runner that can sustain a speed of 15.5 m/s. He went to Laguna Lake and sat on a floating log. When Sandy passed by, he was scared and jumped off the log with a velocity of 15 m/s towards the other side. The log moved with a velocity of 3.8 m/s away from Patrick. If the mass of the log is 250 kg, what is Patrick’s mass?
