A body of mass 0.05kg is observed to fall with an acceleration of `0.95ms^(-2)` ,the opposing force of air on the body is `(g=-9.8m/s^(2))`

A bird of mass 0.1 kg rising vertically with an acceleration 0.2 ms^(-2) . The muscular force exerted by it is (g=9.8 ms^(-2)) (a) 1 Newton (b) 9.8 kg,wt (c ) 1/9.8 kg.wt (d) 980 newtons.

A balloon os mass 2 KG is rising up with an acceleration of 4m/s^2 . The upward force acting on the balloon is (g = 10 ms^-2)

Due to the application of a force on a body of mass 100 kg that is initially at rest, the body moves with an acceleration of 20ms^(-2) in the direction of the force. Find the magnitude of the force.

A lift of mass 100 kg is moving upwards with an acceleration of 1 m//s^(2) . The tension developed in the string, which is connected to lift is ( g=9.8m//s^(2) )

A body of mass 2 kg slides down with an acceleration of 3 m//s^(2) on a rough inclined plane having a slope of 30^(@) The external force required to take the same body up the plane with the same acceleration will be : (g=10 m//s^(2))
