Tom, 75 kg, and John, 95 kg, paddle their 35 kg canoes on the lake. Tom drops his only paddle in the water and it sinks to the bottom when Tom is 15 m from shore. John decides to try to bump Tom to the shore. Assuming the water is still, Tom is initially at rest, and John can move his canoe at 3 m/s, will John be able to bump Tom to the shore? You may use a coefficient of restitution of 0.8 and a coefficient of friction of 0.2 between the water and the boat.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

15m
Tom, 75 kg, and John, 95 kg, paddle their 35 kg canoes on the lake. Tom drops
his only paddle in the water and it sinks to the bottom when Tom is 15 m from
shore. John decides to try to bump Tom to the shore. Assuming the water is
still, Tom is initially at rest, and John can move his canoe at 3 m/s, will John
be able to bump Tom to the shore? You may use a coefficient of restitution of
0.8 and a coefficient of friction of 0.2 between the water and the boat.

A frictionless pulley is used to hoist or lower mass A (100 Kg) vertically upwards as the mass B (50 Kg) is pulled down the rough incline plane (? = 0.25, angle of inclination = 30 degrees) with a force P = 40t N parallel to the incline plane, where t is time in seconds. (a) Draw free body diagrams of mass A and B. (b) Establish the relationship between the velocity and acceleration of the particles. (c) Write down the equation of motion for the particles and determine the acceleration of particles A as a function of time. (d) Given that at t = 0, sA 10m, VA=O, determine when motion of mass A stops and the tension in the cable at that instant.
Feeling adventerous, Jane wants to go bowling on the roof of her apartment building. She starts out on the roof of a 51m tall building, but the bowling pins are set up on the roof of the adjacent building, which is 15 m away horizontally, but only 35m tall. She rolls the bowling with an initial velocity of 1.2 m/s, but the ball then goes down a 1.0 m tall ramp to give it some extra speed, then the ball (with a mass of 6 kg and a radius of 10 cm) rolls without slipping to the edge of the building, and toward the second roof. The moment of inertia of a sphere is (2/5)mr^2. Does the ball reach the pins on the adjacent building? Or is some poor guy going to find that a bowling ball has fallen from the sky to crush his car? Explain your reasoning!
