Bike at rest goes down on a semi- circular track in a skating park. Track has radius of 8.11 m. Using the coefficient of rolling friction and average Normal force, find an estimate for the average lost of energy from the top to the bottom of the track.

Nave= 2690N coefficient of rolling friction = 0.004 mass of rider and bike = 90.5 kg

A block of mass m is initially held at rest at point P on an incline that makes an angle q with respect to horizontal. The coefficient of kinetic friction between the block and the incline is mk. After the block slides down the incline from point P, it starts to slide without friction up a vertical circular track of radius R. When it reaches the top of the circle, the normal force (downward) by the track to the block...

Starting from rest, a kid named Billy goes down a slide, which is a height of 2.5 m above the ground. Billy’s mass is 35 kg. There is friction acting on Billy, so that when he reaches the bottom of the slide (at ground level), his speed is only 3.5 m/s. Consider the total mechanical energy of the Earth + Billy system, which consists of kinetic and potential energy. How much mechanical energy was lost due to friction? Give your...

A 117 kg seal at an amusement park slides from rest down a ramp into the pool below. The top of the ramp is 1.85 m higher than the surface of the water and the ramp is inclined at an angle of 26.5 ∘ above the horizontal. If the seal reaches the water with a speed of 4.10 m/s, what is the work done by kinetic friction? What is the coefficient of kinetic friction between the seal and the ramp?

10.4-5-6) A) A car traveling on a flat (unbanked), circular track accelerates uniformly from rest with a tangential acceleration of 2.10 m/s2. The car makes it one quarter of the way around the circle before it skids off the track. From these data, determine the coefficient of static friction between the car and track. ________ (Hint: You are not given a value of the radius of the track. Think through the problem using the symbol R for this value and...

1.A small block of mass 3.5 kg starting from rest slides down on an incline plane of height 2.0 m, 40 degrees with respect to horizontal (Fig. 2). The coefficient of kinetic friction between the block and the incline plane is 0.25. At the end of the incline plane, the block hits the top of a hemispherical mound of ice (radius 1.0 m) , loses 75% of final kinetic energy (KE=0.5mv*v) before the collision, then slide down on the surface...

1. A cylindrical wooden log rolls without slipping down a small ramp. The log has a radius of 16 cm, a length of 2.5 m, and a mass of 130 kg. The log starts from rest near the top of the ramp. When the log reaches the bottom of the ramp, it is rolling at a linear speed of 2.3 m/s. a.) Assuming that the log is a perfect cylinder of uniform density, find the log’s moment of inertia (about...
