The distance x m travelled by a particle in time t seconds is described by the equation x = 10 + 12t\(^2\), Find the average speed of the particle between the time interval t = 2s and t = 5s
A 5kg block is released from rest on a smooth plane inclined at an angle of 30o to the horizontal. What is the acceleration down the plane? [g = 10ms-2]
An arrow of mass 0.1kg moving with a horizontal velocity of 15ms-1 is shot into a wooden block of mass 0.4kg lying at rest on a smooth horizontal surface. Their common velocity after impact is
