1. A 500kg car moves along a road. When it passes through point A (30 meters), its speed is 15 m / s, while passing through point B (18 meters) its speed is 8m / s. Calculate how much heat is produced due to friction between roads and car wheels.
2. A pendulum has a 4kg mass attached.The initial angle is 20 degrees and the initial speed is 0, when the object passes through the lower point (angle 0) of its trajectory, its speed is 3.6m / s. Calculate the length of the pendulum.

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...

A car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...

A speeding car is traveling along a straight road with a constant speed of 100 km/hour. It passes a police car. The police car starts 5.00 s after the speeder passes. The police car accelerates uniformly (i.e. at constant acceleration) for 10.0 s, at the end of which its speed is 120 km/hour. After that, the police car moves with the constant speed of 120 km/hour till it reaches the speeding car. a) How far ahead of the police car...
