Q. Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 125 kg. Under the influence of a drive force of 235 N, it is moving at a constant velocity whose magnitude is 4.23 m/s. The drive force is then shut off. Find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so.
Q. An electron moves at a speed of 6.0 x 10^-6 perpendicular to a constant magnetic field. The path is a circle of radius 1.3 x 10^-3m. What is the magnitude of the field. Find the magnitude of the electron acceleration.
A block of mass .250 kg traveling at (1.0 m/s)y hits a second block with a .375 kg mass travelling at (1.2m/s)x.
A uniform plank of length 5.40 m and weight 217 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support. To what distance x can a person who weighs 417 N walk on the overhanging part of the plank before it immedia..
A motorist drives south at 30.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.80 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.8 min trip, how do you find the total vector, average speed and average velo..
