Part 1) A small block travels up a frictionless incline that is at an angle of 30.0°above the horizontal. The block has speed 4.26 m/s at the bottom of the incline. Assume g = 9.80 m/s2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down? Part 2) Complete the following exercises. (Assume g = 9.80 m/s2.) (a) A small block is released from rest at...

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
