A bike of mass 200 kg (with rider) is running on the road with constant speed `5 m//s`, the reaction exerted on the bike by the road at the lowest point will be (`g= 10 m//s^(2)`)

In the above problem, the force exerted by the pilot on the seat at the lowest point of the circle will be [Take g=10 m//s^2 ]

A ring of mass 1kg and diameter 1m is rolling on a plane road with a speed 2m/s. Its kinetic energy would be -

A rocket of mass 5700 kg ejects mass at a constant rate of 15 kg/s withe constant speed of 12 km/s. The acceleration of the rocket 1 minute after the blast is (g=10m//s^(2))

A stone of mass 1 kg tied to a string 4 m long and is rotated at constant speed of 40 m/s a vertical circle. The ratio of the tension at the top and the bottom, is (g=10" m"//"s"^(2))

A lorry of mass 2000 kg is traveling up a hill of certain height at a constant speed of 10 m/s. The frictional resistance is 200 N, then the power expended by the coolie is : (g=10 m//s^(2))

An object of mass 2 kg is whirled rround in a verticle circle of radius 1m with a constant speed of 4 m//s .Then the maximum tension in the string is (g=10 m//s^(2))

A block of mass 1 kg is at rest relative to a smooth wedge leftwards with constant acceleration a =5 m//s^(2) .Let N be the normal reaction between the block and the wedge. Then ( g = 10 m//s^(2) )

A man of mass 65 kg is holding a bucket of mass 15 kg. He walks 50 m on a level road at a constant speed of 3 m/s and then climbs up a hill of height 20 m. What is the work done by the man? Take g = 10 m/s^2 .

An aeroplane flying in the sky with a uniform speed of 200 m//s moves in a vertical circle of radius 400 m. The mass of the pilot is 70 kg. The force exerted by the pilot on the seat at the highest point of the circle will be [Take g=10 m//s^2 ]
