Sam, whose mass is 75 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 200 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 10 s. What is Sam's top speed? (in meters/second)How far has Sam traveled when he finally coasts to a stop? (in meters)
An object attached to a horizontal spring is oscillating back and forth along a frictionless surface. The maximum speed of the object is 1.75 m/s, and its maximum acceleration is 7.79 m/s2. How much time elapses betwen an instant when the object's sp..
Point O is the source of the sound that vibrates constantly resulting in a wave running from O to P propagating at the speed of 80 m / s, amplitude of 14 cm and a frequency of 20 Hz. Point Q is 9 m from O. if the point O has vibrate 16 times, calcula..
