A bicycle and its rider have a total mass of 83.0 kg. Each of its wheels can be modeled as a thin hoop with mass 1.32 kg and diameter of 70.0 cm. When the brakes are applied, two brake pads squeeze the rims of each wheel. Assume that the four brake pads exert normal forces on the wheels that are equal and constant in magnitude. The coefficient of kinetic friction between a brake pad and a wheel is 0.900. The...

An automobile has a mass of 2300 kg and a velocity of positive 16 m/s. It makes a rear end collision with a stationary car whose mass is 1800 kg. The cars locked bumpers and skid off together with the wheels locked. A) what is the velocity of the two cars just after the collision. B) find the impulse, magnitude and direction, the acts on the skidding cars from just after the collision until they come to a halt. C)...

Section B a. A bicycle and a rider have a combined mass of 175 kg. How many calories of heat are generated in the brakes when the bicycle comes to a stop from a speed of 20 m/s? Take 4.18 J =1cal             b.  If all the energy is trapped in a 1.5 kg aluminum bag without any heat       loss, how much will its temperature increase (DT) ? c = 0.220 cal/g°C.

Bob is driving his car at 20 m/s down a hill with a slope of 5 degrees. When a deer suddenly jumps out of the woods onto the road, he slams on the brakes, and the car skids to a stop. The mass of the car is 1500 kg, and the coefficient of kinetic friction between the tires and the road is µk = 0.816. a) (3 points) Draw a free-body diagram for the car. b) (3 points) Determine the...

A 2300 kg car moving at an initial speed of 25 m/s along a horizontal road skids to a stop in 50 m. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes. With regenerative braking, such as that used in hybrid vehicles, only 70 percent of the kinetic energy is dissipated.) (a) Find the energy dissipated by friction. 718750 Incorrect: Your answer is incorrect. kJ (b) Find...

A bicycle and its owner roll down a hill dropping in altitude 4.0 m, ending up on level ground. The mass of the cycle plus bicyclist is 70.0 kg. We ignore the effect of friction in the first two questions. A. If the bicycle starts initially at rest, find the speed of the bicycle when it reaches level ground. B. If instead the bicycle starts with an initial speed of 4.0 m/s, find the speed of the bicycle when it...
