A barge on a still lake is moving toward a bridge at 10 meter per second. When the bridge is 39.5 meter away, the pilot slows the boat with a constant acceleration of 0.79 m/s2.
(a) Use x = x0 + v0t + 1/2at2 to obtain the time it takes the barge to reach the bridge.
(b) Obtain the final velocity for each time using v = v0 + at.
Consider a single electron, with a mass of 9.1×10?31kg , subject to a single force equal to the weight of a penny, 2.5×10?2N
A circular coil of radius 6.0 cm has 1500 turns and a total resistance of 0.25. Initially it is in a region with a uniform magnetic field of 0.25 T perpendicular to the coil area. Find the average emf induced in the coil
Piles of snow on slippery roofs can become dangerous projectiles as they melt. Think a chunk of snow at the ridge of a roof with a pitch of 30 degrees. Because the snows begin to melt it will eventually slip.
A rock is dropped from a tree of height 24 m into a lake (depth 6.0 m) below. What is the total elapsed time
Discuss briefly centripetal acceleration, the speed and the force exerted by a ball attached to a string.
A very large plane of charge is oriented horizontally and has a constant charge distribution over the plane. A small insulating ball has charge +8.78 nC and mass 0.076 g. If the levitates 2.62 cm beneath the plane, and remains stationary, what is the..
14g of nitrogen gas at 0°C and 1 atm is compressed in an isochoric process to an pressure of 20 atm. How much heat is inputted into the gas
Consider the system shown in the figure below with m1 = 24.0 kg, m2 = 10.7 kg, R = 0.250 m, and the mass of the pulley M = 5.00 kg. Object m2 is resting on the floor, and object m1 is 4.40 m above the floor when it is released from rest. The pulle..
A 2.35kg ball moving at 4.20 m/s to the right hits a 3.45kg ball head on that is travelling at 3.50 m/s to the left. What is the velocity of the first ball after the perfectly elastic collision
In a skating stunt known as "cracking-the-whip," a number of skaters hold hands and form a straight line. estimate the magnitude of the centripetal force that acts on him
