A 24 kg block slides with an initial speed of 6 m/s up a ramp inclined at an angle of 20o with the horizontal. The coefficient of kinetic friction between the block and the ramp is 0.6. Use energy conservation to find the distance along the incline that the block slides before coming to rest.
Carbon tetrachloride (n=1.46) is poured into a container made ofcrown glass (n=1.52). what is the angle of the corresponding refracted ray
A 72.3 kg man carrying a 5.23 kg box gets on an elevator. As the elevator accelerates upwards at 0.224 m/s^2, he feels the box is heavier, During this time, what is the weight on the floor from his feet
A father racing his son has 1/3 the kinetic energy of the son, who has 1/3 the mass of the father. The father speeds up by 1.5 m/s and then has the same kinetic energy as the son.

In a series RCL circuit the dissipated power drops by a factor of 8.0 when the frequency of the generator is changed from the resonant frequency to a nonresonant frequency
After fixing a flat tire on a bicycle you give the wheel a spin. (a) If its initial angular speed was 6.09 rad/s and it rotated 15.8 revolutions before coming to rest, what was its average angular acceleration? rad/s2 (b) For what length of time d..
A 1380-kg racecar is driving around a circular track of radius 157 m, What is the magnitude of the net force acting on the vehicle at this time and the force's direction relative to the velocity
