- A 2-kg brick is thrown downward from a height ?1 = 15 m to ?2 = 10 m. The initial kinetic energy of the brick is ??1 = 25 J. You can use ? = 10 m/s for convenience of calculation. Assume air resistance is negligible, and nothing heats up or uses fuel during the motion of the brick.1. If the system of interest is the brick alone, how much work is done by external forces during this motion?Computation. A 6.24-kg snake slithers at constant speed all the way around a circular path of radius 2.37 m. The coefficient of friction between the ground and the snake is 0.32.

XA car is parked on a hill. The gravitational force on the car is 9.31 x 103 N straight downward, and the angle of the hill is 4° from the horizontal. The car’s brakes fail, and the car slides 30.0 m downhill. a) Calculate the component of the gravitational force that acts parallel to the car’s motion. b) Calculate the work done on the car by gravity as the car slides.

- A crate is placed at the upper end of the 2.0 m long ramp that is inclined at 20° to the horizontal and allowed to slide down the ramp starting from rest. The crate has a mass of 150 KG and the coefficient of kinetic friction between the crate and then incline is 0.25. Draw a diagram showing all the forces acting on the crate. How much work is done by the gravity on the crate during the slide? How much work is done by friction during the slide? Use the work energy theorem to calculate the speed attained at the bottom of the ramp.Also,Which force does no work during the slide, and why?14.
