Q.A person can jump a horizontal distance of 3.20 m on Earth, where the free-fall acceleration, g = 9.81 m/s2.
(a) How far could the person jump on the moon, where the free-fall acceleration is g/6
(b) How far could the person jump on Mars where the acceleration due to gravity is 0.38g?
Q. A force of 40.0 N is used to pull a 10.0-kg wooden block at a constant velocity across a smooth glass surface on Earth. what force would be required to pull the same wooden block across the same glass surface on the planet Jupiter.
A parallel-plate air capacitor with a capacitance of 245 has the charge of magnitude 0.1502 on each plate. The plates have the separation of 0.323.
A 60kg pole vaulter running at 13m/s vaults over the bar. Her speed when she is above the bar is 0.7m/s. Neglect air resistance, as well as any energy absorbed by pole, and determine her altitude as she crosses the bar.
A straight, stiff wire of length 1.00 m and mass 21g is suspended in a magnetic field B = 0.58T. The wire is connected to an emf. How much current must flow in the wire and in what direction so that the wire is suspended and the tension in the sup..
A caterpillar climbs up a one-meter wall. For every 3 cm it climbs up, it slides down 1 cm. It takes 10 minutes for the caterpillar to climb to the top. Compute the speed at which the caterpillar travels.
An electric motor rotating a workshop grinding wheel at a rate of 9.90 x 10^1 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 1.70 rad/s2.
An explorer in dense jungles of equatorial Africa leaves his hut. He takes 41 steps at an angle 45 north of east, then 81 steps at an angle 60 north of west, then 51 steps due south. Suppose his steps all have equal length. Save him from becoming ..
What is the greatest mass that can be accelerated upwards at 2.9 m/s2 if the stress in the cable is not to exceed the elastic limit of the cable, that is 2.2 108 Pa.
Where does package hit the ground relative to the point
A swimmer heads directly across a river, swimming at 1.9 m/s relative to the water. She arrives at a point 34 m downstream from point directly across the river, which is 80 m wide.
Compare the kinetic energy of car travelling. Compare the kinetic energy of an 900 kg car travelling at 30 m/s, and a 1,800 kg car at the same speed.
Compute the horizontal distance
A block with mass m = 19.0 kg slides down an inclined plane of slope angle 17.8 ° with a constant velocity. It is afterwards projected up the same plane with an initial speed 1.35 m/s. How far up the incline would the block move before coming to rest..
