A 100kg truck is pulled across rough ground by a rope angled at 30 degrees to the horizontal. The coefficient of sliding friction is .34. Find the maximum Acceleration without the truck leaving the ground.
A 30.0g ball rolls around the 40.0cm diameter hemishperical track at 60.0rpm. Assume rolling friction is negligible. Determine the ball's linear velocity
Charged particles pass through a velocity selector with electric and magnetic fields at right angles to each other, as shown in the figure. If the electric field has a magnitude of 490 N/C and the magnetic field has a magnitude of 0.14 T, what speed ..
A 1.80Kg brick is sliding next to on a rough horizontal surface at 13.5m/s .If the brick stops in 4.80, how much mechanical energy is lost.
A 45.0 kg person, standing 1.3 m from the axis, begins to run on the disk in a circular path and has a tangential speed of 2.80 m/s relative to the ground. Find out the resulting angular speed of the disk (in rad/s)
The system shown below has frictionless pulleys and the string have negligible mass. what is the speed of the objects when they are at the same height
This bat hears its own sound plus the sound reflected by the wall. Explain how fast should the bat fly in order to hear a beat frequency of 10.0Hz?
A passenger in the car, who has a mass of 45 kg, moves forward a distance of 55 cm while being brought to rest by inflated air bag. what is the magnitude of force acting on the passenger
A ball dropped from a height of 4.00 m makes an elastic collision with the ground. Assuming no mechanical energy is lost due to air resistance, a) show that the ensuing motion is periodic, b) find the period of the motion.
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26.
A snowboarder starts from rest rides 30.31m down a snow covered slope that makes an angle of 34.19 degrees with the horizontal, How far will she travel along the flat snow
A disk of radius 3.00 cm has a uniformly distributed charge of Q = 5.20 uC, Calculate the electric field on the perpendicular axis of disk
