Problem: An object is sliding on incline plane. The angle of inclination, mass of the object, the distance the object has slid, and the coefficient of kinetic friction are given.
Part A: You need to calculate work which is done by friction force.
I want help to calculate work which is done by friction force.
A highway curves to the left with radius of curvature of 44 m and is banked at 29degrees so that cars can take this curve at higher speeds. Consider a car of mass 1387 kg whose tires have a static friction coefficient 0.68 against the pavement.
For comparison, what is the magnitude of the acceleration a test tube would experience if dropped from a height of 1.0 m and stopped in a 2.0-ms-long encounter with a hard floor
The position of an object connected to a spring varies with time according to the expression x = (4.4 cm) sin(6.9?t). (a) Find the period of this motion.
A spring with spring constant 17N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. What is the mass of the ball

A firefighter mounts the nozzle of his fire hose a distance 40.1 m away from the edge of a burning building so that it sprays from ground level at a 45° angle above the horizontal. By what factor was the nozzle diameter changed
A vertical straight wire carrying an upward 24A current exertsan attractive force per unit length of 8.8e-4 N/m on a secondparallel wire 7cm away. What current (magnitude anddirection) flows in the second wire
A pail of water is rotated in a vertical circle of radius 1.20 m. What is the minimum speed of the pail at the top of the circle if no water is to spill out
A cylindrical aluminium rod is attached to a wall by a hinge. A copper cable is attached to the rod at point three-quarters of its length away from the wall and used to support the rod in a horizontal position.
A baseball is bunted down the third-base line leaving the bat from a height of 0.850m with an initial velocity of 4.00m/s at an angle of 37.87° above horizontal.
