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.

3. An automobile moving at a constant velocity of 45 ft
per sec passes a gasoline station. Two seconds later,
another automobile leaves the gasoline station and
accelerates at the constant rate of 6 ft per sec?. How

A villain in a car traveling at 30 m/s fires a projectile along the direction of motion toward the front of the car with a launch speed of 50 m/s relative to the car.

Human centrifuges are often used to simulate different acceleration levels for pilots. When aerospace physiologists say that a pilot is pulling 9 g,s , they mean that the resultant normal force on the pilot from the bottom of the seat is nine times their weight. Knowing that the centrifuge starts from rest and has a constant angular acceleration of 1.5 RPM per second until the pilot is pulling 9 g's and then continues with a constant angular velocity, determine (a) how long it will take for the pilot to reach 9 g's (b) the angle 0 of the normal force once the pilot reaches 9 g’s. Assume that the force parallel to the seat is zero.
A car and truck are both traveling with a constant speed of 20m/s. The car is 10m behind the truck. The truck driver suddenly applied his brakes, causing the truck to decelerate at the constant rate of 2m/s. Two second later the driver of the car applied his brakes and just manages to avoid a rear-end collision. Determine the constant rate at which the car decelerated.

A motorcycle starts from rest at t=0 and moves along a circular track with a radius of 400 m. The tangential component of its acceleration is at= 2 m/s2. When the magnitude of its total acceleration reaches 5 m/s2, friction can no longer keep the motorcycle on the circular track, and it spins out. Can the motorcycle complete one quarter of a lap of the track before it spins out? Justify your answer with relevant calculations.
