Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.20×106N , one at an angle 13.0? west of north, and the other at an angle 13.0? east of north, as they pull the tanker a distance 0.890km toward the north.
Find: What is the total work done by the two tugboats on the supertanker?
A force vector has a magnitude of 577 newtons and points at an angle 43o of below the positive x axis. What is (a) x scalar component and (b) y scalar component of the vector.
A parallel plate capacitor (air filled) that is maintained at a 20.0 V potential difference between plates, Calculate the surface charge density, and the charge on each plate
A car is moving at a constant velocity for 3s until it is 3.0 m from a yellow light. It slows to a stop in 2.0s. It remains stopped for 50s and then speeds up for 2s.
The coefficients of static and kinetic friction between a 67 kg box and a horizontal surface are 0.56 and 0.32, respectively. Illustrate what is the acceleration of the object if a 335 N horizontal force is applied to the box?
A particle of charge +9.2 ?C is released from rest at the point x = 55 cm on an x axis, What is the kinetic energy of the particle at the instant it has moved 12 cm if Q = +61
The cars stick together and move as a unit after the collision, at an angle of 47.0° north of east and at a speed of 6.36 m/s. Find out the speed of the 3000 kg car before the collision.

A 0.20 kg aluminium plate with an initial temperature of 20 degrees c slides down a 15.00m long surface that is inclined at 30 degrees to the horizontal.
Assume that we suddenly discovered that all these years we would be wrong about the distance from Earth to the Sun, and it is actually 10 percent greater than we would think. How would that affect our approximation of the distance to the Andromeda..
A 25- sample of an ideal gas with is at 250 and 50. The gas is compressed isothermally to one-third of its original volume, then heated at constant volume until its state lies on the adiabatic curve that passes through its original state, and then al..
