A block of mass 500 g is at rest on a horizontal table. What steady force is required to give the block a velocity of `200 cms^(-1)` in 4 s?

Text Solution

Verified by Experts

Use `F = ma `
` a = (v - u)/(t ) = (200 - 0)/(4) = 50 cm//s^2`
` F = 500 xx 50 =25,000 `dyne

A block of mass 2.5 kg is kept on a rough horizontal surface. It is found that the block does not slide if a horizontal force less than 15 N is applied to it. Also it is found that it takes 5 seconds to slide through the first 10 m if a horizontal force of 15 N is applied and the block is gently pushed to start the motion. Taking g=10 m/s^2 , calculate the coefficient of static and kinetic friction between the block and the surface.
