Physics 1D03 2009 Tutorial Exercises 3 Name_____________________________ Student Number_____________________ 1. A block of mass 2.50 kg is pushed 2.20 m along a frictionless table by a constant 16.0 N force directed 25 o below the horizontal. Determine the work done on the block by: a) the applied force b) the normal force exerted by the table c) the gravitational force d) Determine the net work done on the block. 2. A force F = (6 i – 2 j ) N acts on a particle that undergoes a displacement r = (3 i + j ) m. Find the work done by the force on the particle.

Unformatted text preview: force between the box and the floor of 5.00 N 4. A spring with spring constant k is compressed by a distance x , which requires work W . How much work would be required to compress the spring: a) to 2 x ? b) to 5 x ? c) from 2 x to 5 x ? 5. A particle is subject to a force F x that varies with position as shown in the figure below. Find the work done by the force on the particle as it moves: a) from x=0 m to x=5.00 m b) from x=5.00 m to x=10.0 m c) from x=10.0 m to x=15.0 m d) What s the total work done by the force over the distance x=0 m to x=15.0 m?...
