Q. A force vector has a magnitude of 590 newtons and points at an angle 44o of below the positive x axis. What is (a) x scalar component and (b) y scalar component of the vector?
Q. An airplane should reach a speed of 184mi/h to take off. If the runway is 484 m long, what is the minimum value of the acceleration that will allow the airplane to take off successfully?
Find the charge on sphere A. How far from the dog will the suitcase land.
Compute the mass of a ball and speed of a puck after collision.
Find the distance from the positive plate

A paperweight is made of a solid glass hemisphere with index of refraction 1.50. The radius of the circular cross section is 4 cm. The hemisphere is placed on its flat surface, with the centre directly over the 2.5 mm long line drawn on a sheet of ..
find out the magnitude of their acceleration. If the blocks move determine the magnitude of the tension in the string. If the blocks do not move determine the sum of magnitude of the forces of friction acting on the blocks. Show all the work.
A rocket ship at rest in space gives a short blast of its engine, firing 90 kg of exhaust gas out the back end with an average velocity of 700 m/s.
What is the initial (horizontal) velocity of the ball.
Consider the 642 N weights held by two cables shown. The left-hand cable had tension T2 and makes an angle of thelta2 with ceiling. The right-hand cable had tension 460 N and makes an angle of 47 degrees with the ceiling.
A 2.00×10-2- cube of ice at an initial temperature of -19 is placed in 0.670 of water at 44.0 in an insulated container of negligible mass.
By how much does the ball clear the net. How far below top surface would the medallion appear if the observer (not wearing goggles) and the block were under water.
