Answer. The impluse on the ball acts perpendicular to the smooth plane. (i) The component of velocity of ball parallel to the surface. (ii) For the component of velocity of ball perpendicular to the surface, apply law of restitution. The component of velocity parallel to the surface will be changed. v cos α = u cos 60°. v cos α = 5 × 1/2 = 5/2 ….
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
11 lut 2022 · Find the amount of work done by a labourers who carrier ‘n’ bricks of ‘m’ kg each to the roof of a house ‘h’ metre high by climbing a ladder. Q.10. A force of 5 N acts on an object. The object id displaced through 8 m, in the direction of the force.
Work, Energy, and Power © The Physics Classroom, 2020 Page 2 remembered when solving such work problems. The amount of work (W) done on an object by a given force can be calculated using the formula W = F d cos Q where F is the force and d is the distance over which the force acts and Q is the angle between F and d. It is important to ...
