Q1. A tow truck pulls a car 5.2 km along a horizontal roadway using a cable having a tension of 790.
a)How much work does cable do on the car if it pulls horizontally?
b) How much work does cable do on the car if it pulls at 35.0^circ above the horizontal?
c) How much work does cable do on the tow truck if it pulls horizontally?
d) How much work does cable do on the tow truck if it pulls at 36.0^circ above the horizontal?
e) How much work does gravity do on the car in part A?
Q2. Two railroad cars, each of mass 6500kg and travelling 95km/h in opposite directions, collide head-on and come to rest. How much thermal energy is produced in this collision?
An object of mass m is attached to a horizontal spring, stretched to a displacement A from equilibrium and released, undergoing harmonic oscillations on a frictionless surface with period T0. The experiment is then repeated with a mass of 4m. The sub..
Assume that the rod is held at rest horizontally and then released. (Throughout the remainder of this problem, your answer may include the symbol, moment of inertia of the assembly, whether or not you have answered the first part correctly.)
A small spherical insulator of mass 8 x 10 kg and change +0.600 micro Coulomb is hung by a tin wire of negligible mass. A charge of -0.900 micro Coulomb is held 0.150 m away the sphere and straight to the right of it, so the wire makes the angle with..
How far would trampoline stretch if the performer stands still on it while taking a bow.
Compute coefficient of kinetic friction
The loaded cab of an elevator has a mass of 3.0 x 10^3 kg and moves 145 m up the shaft in 23 s at constant speed. At what average rate does the force from the cable do work on the cab.
Young's double-slit experiment is performed with 570 nm light and a distance of 2.00 m between the slits and the screen. The tenth interference minimum is observed 7.64 mm from the central maximum. Settle on the spacing of the slits.
A 130 block on a frictionless table is firmly attached to one end of a spring with = 40. The other end of the spring is anchored to the wall. A 21 ball is thrown horizontally toward the block with a speed of 6.6.
The alpha line in the Balmer series of the hydrogen spectrum consists of light having a wavelength of 6.56 ×10-7 meter. Compute the frequency of this light.

Problem on elevator
What is magnitude of the force that a concrete support exerts on the bridge at each end. The cloth exerts a friction force of 0.100 N on the mug and the cloth is pulled with a constant acceleration of 3.00 m/s.
