Q. What is the size of the smallest vertical plane mirror in which a 10.0 tall giraffe standing erect can see her full-length image? (Hint: Locate the image by drawing a number of rays from the giraffe's body that reflect off the mirror and go to her eye. Then eliminate that part of the mirror for which the reflected rays do not reach her eye.)
Q. If a mechanic tightens the spark plug with a wrench that is 31 {rm cm} long, what is the minimum force necessary to create the desired torque? if a mechanic tightens the spark plug with a wrench that is 31 {rm cm} long, what is the minimum force necessary to create the desired torque?
A soccer ball with a mass of 448g bounces off the crossbar of a goal and is deflected upward at an angle of 56.2° with respect to horizontal. Immediately after deflection, the kinetic energy of the ball is 47.70 J. What are the vertical and horizo..
A canoe has a velocity of 0.54m/s southeast relative to the earth. The canoe is on a river that is flowing at 0.52m/s east relative to earth.
What are the corresponding velocity vectors
How much work did the movers do (horizontally) pushing a 190-{rm kg} crate 11.2 m across a rough floor without acceleration, if effective coefficient of friction was 0.60.
A person exerts a horizontal force of F = 169N in the test apparatus. (h = 0.32m.) Find the horizontal force M that his flexor muscle exerts on his fore arm.
Find the typical speed for a tsunami. (Note down that in the open ocean, tsunamis generally have amplitude of less than a meter, allowing them to pass ships unnoticed. As they approach shore, however, water depth decreases and the waves slow down. Th..
A stone has a mass of 6.0 x 10-3 kg and is wedged into the tread of an automobile tire, as the drawing shows. The coefficient of static friction between the stone and each side of the tread channel is 0.90.
A railroad car of mass 4.0 * 10^4 kg moving at 5.0 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.50 m/s.
Find out the resulting values of the processional rate
A 78-kg base runner begins his slide into second base when he is moving at a speed of 4.2 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches base.
The speed of light in a transparent medium (such as glass) is less than the speed of light in a vacuum. Is this a violation of the theory of relativity.
Two 5000 kg passenger cars roll without friction (one at 1 m/s, the other at 2 m/s) toward one another on a level track. They collide, couple, and roll away together with the combined momentum.
