A body starts slipping down an incline and moves half meter in half second. How ling will it take to move the next half meter?

A body starts slipping down an incline and moves half meter in half second. How ling will it take to move the next half meter?

A body starts rolling down an inclined plane , the top half is rough . Find the ratio of the force of friction and weight of the body if the body is brought to rest just when it reaches the bottom , the angle of the plane being 30^(@) .

A train is moving at the speed of 36 km/hr. How many seconds it will take to cover a distance of 600 meters?

Hugo lies on top of a building, throwing pennies straight down to the street below. The formula for the height in meters, H, that a penny falls is H=Vt+5t^(2) , where V is the original velocity of the penny (how fast Hugo throws it as it leaves his hand in meters per second) and t is equal to the time it takes to hit the ground in seconds. The building is 60 meters high, and Hugo throws the penny down at an initial speed of 20 meters per second. How long does it take for the penny to hit the ground?

A body of mass m starts sliding down an incline of 30^(@) from rest. The body comes to rest just when it reaches the bottom. If the top half of the plane is perfectly smooth and the lower half is rough, find the force of friction :

The upper half of an inclined surface is perfectly smooth but the lower half is rough . A body starts sliding down the plane and stops immediately on reaching the bottom. The inclination of the plane is 30^(@) with the horizontal. Show that the frictional resistance of the rough part of the surface is equal to the weight of the body.

A box of mass 25 kg starts from rest and slides down an inclined plane 8 meter long and 5 meter high. It is found to move at the bottom at 7 m/s. What is the force of friction
