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

A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial velocity of 11.5 m/s
and accelerates at the rate of 0.500 m/s² for 7.00 s.
(a) What is his final velocity?
Answer:
(b) The racer continues at this velocity to the finish line. If he was 300 m from the finish line when he
started to accelerate, how much time did he save?
Answer:
m/s
(c) One other racer was 5.00 m ahead when the winner started to accelerate, but he was unable to
accelerate, and traveled at 11.8 m/s until the finish line. How far ahead of him (in meters and in seconds)
did the winner finish?
Answer:
m or
S

Q16. A 3.4-kip car speeds up uniformly from 0 to 57 mph in 39 seconds up the 15⁰ incline. If the engine has an efficiency of e = 0.73, what is the power input (in hp) when the car's speed reaches that final speed? (1 hp = 550 ft-lb/s) Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 32.2 ft/s². Your Answer: Answer 15°
4) You were leisurely flying your F-18 when you encounter an alien aircraft. The alien was flying at an altitude of 3 km while you were at an altitude of 600 m. You begin to increase your speed at a rate of 2.0 m/s?. You are traveling at a speed of 750 km/h at the instant when 0 = 45° and at the same instant the alien has a constant velocity of 1,500 km/h. a) Determine the velocity and acceleration vectors (in m/s and m/s², respectively) of the alien as observed by you. [Ans. to Check: VB/A = 208.4 įm/s] b) Determine the time rate of change of the vector r that is between you and the alien ship in m/s. In other words, find r. [Ans. to Check: i = 147.32 m/s] Hint: Do not forget about your ability to dot in different directions to eliminate variables from the equation. c) Calculate the angular velocity of the spaceship relative to you in rad/s. d) Determine the radial and angular accelerations in m/s? and rad/s².
