A racecar is driving around a circular turn on a racetrack that has a radius of 35 m. Their initial angular velocity entering the turn is 0.785 rad/s. If the coefficient of kinetic friction between the 1,500 kg racecar and the racetrack is u = 0.5, calculate the velocity (in km/hr) of the driver as they exit the turn. Assume it takes them 4 seconds to go around the bend. For full credit, draw an FBD and clearly define your system using polar coordinates. [Ans. to Check: 28.28 km/hr) 1131 AM

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

1) Aracecar is driving around a circular turn on a racetrack that has a radius of 35 m. Their initial
angular velocity entering the turn is 0.785 rad/s. If the coefficient of kinetic friction between
the 1,500 kg racecar and the racetrack is µ = 0.5, calculate the velocity (in km/hr) of the driver
as they exit the turn. Assume it takes them 4 seconds to go around the bend. For full credit,
draw an FBD and clearly define your system using polar coordinates. [Ans. to Check: 28.28

A car A is stuck on the railroad tracks as a train B approaches with a speed of 120 km/hr. As soon as the problem is detected, the train's emergency brakes are activated, locking the wheels and causing the train's wheels to slide relative to the tracks. If the co-efficient of kinetic friction between the wheels and the track is 0.2, use work energy principle to determine the minimum distance d at which the brakes must be applied to avoid a collision under the following circumstances. Mass of the train is 195,000 kg. A B d
Body U with mass 5m is stacked on the top body W with mass m, and released. The bodies are in contact along the frictionless interface at 45° to the vertical. The body U is in contact with the frictionless vertical wall. Body W lies on the floor with coefficient of friction u. Relevant dimensions are shown in the figure. Express the results in terms of given quantities: m, g, h and µ (except when µ is given numerically). You need not evaluate sin 45° = cos 45° = 2/2. h U: 5m C 45 D W: m 3h
Determine the speed of block in Q1 when it moves 2m up the slope using the Work and Energy method and calculate the power of the force P. (If you can apply the principle of work and energy or conservation of enegry.) Plus can you not use the required method for this question. Question 1: A 5kg block is pushed up along the slope as shown. The coefficient of kinetic friction is uk =0.2. Determine the speed of the block when it moves 2 m up the slope using Newton's Second Law. I also gave the answer for Q1 if it helps: V = 2.21m/s

2. A block travels past point A with a speed of 8 m/s along a smooth surface until it reaches a rough surface of length L=20 m and a coefficient of kinetic friction of 0.8. If the height h₁ = 8 m, and h₂ = 3 m. Determine (A) the speed of the block at point B (B) whether the speed at point C (C) reaches point D. If so, what is the speed at point D, if not, how far is the rough surface that cross the beam?
