A 15kg crate is moved along a horizontal floor by pulling on it with a rope that makes a 30 degree angle with the horizontal. The tension in the rope is 200N and the crate slides a distance of 10m. If the coefficient of kinetic friction between the crate and the floor is 0.4
A) How much work is done by the normal force
B) How much work is done by frictional force
C) How much work is done on the crate by the rope
D) What is the net work?
Conclude the magnitude of angular acceleration
Speedboat A negotiates a curve whose radius is 150 m. Speedboat B negotiates a curve whose radius is 190 m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
An 18-year-old runner can complete a 10.0 km course with an average speed of 4.30 m/s. A 50-year-old runner can cover the same distance with an average speed of 3.85 m/s. How much later (in seconds) should the younger runner start in order to fini..
The resistance of a copper wire of length L meter is 0.1 ohms. If the diameter of the wire is 0.045cm, find out its specific resistance.
What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
A 13000 kg railroad car travels alone on a level frictionless track with a constant speed of 17 m/s. A 6500 kg load, originally at rest, is dropped onto the car. What will be the car's new speed.
A meterstick is at rest in an inertial frame S2. If S2 moves with a speed of 0.7c with respect to a rest frame S1, find the length of the meterstick as measured in frame S1 according to classical physics. Reply in units of m.
how high above the target must the rifle barrel be pointed.
Find out the critical angle for the glass-synthetic interface (same as for the glass-diamond interface). Sketch a picture of the incoming ray as it interacts will all subsequent interfaces.
Besides the gravitational force, a 3.25-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (4.10 - 3.30) m, where the direction of is the upward vertical direction. find out ..
A 4.00-g bullet is moving horizontally with a velocity of +355 m/s, where + sign indicates that it is moving to the right. The bullet is approching two blocks resting on a horzizonta frictionless surface.
