A block of mass 5 kg is dropped from top of a building. Then the mamiitude of force applied by the block on the earth whne falling is :

In given arrangement acceleration of each block is :-

A block of mass 1 kg in kept on a rough horizontal surface with mu_(s)=0.1 . A force of 0.5 N is applied as shown in the figure. What is the frictional force applied by ground on the block?

A man of mass 80kg pushes a box of mass 20kg horizontally. The man moves the box with a constant acceleration of 2m//s^(2) but his foot does not slip on the ground. There is no friciton between the box and the ground, whereas there is sufficient friction between the man's foot and the ground to prevent him from slipping. Assertion :- The force applied by the man on the box is equal and opposite to the force applied by the force applied by the box on the man. Reason :- Friction force applied by the ground on the man is 200N .

In the previous problem. The friction force applied by ground on block B is

Calculate the force P required to cause the block of weight W_(2)=200N just to slide under the block of weight W_(1)=100N shown in figure-2.43. What is the tension in the string AB and the normal forces acting between the blocks and that applied by ground on W_(2) ? Surfaces of the blocks in contact are rough and the frictional force between the two blocks is 25 N and that between lower block and ground is 75 N Take g = 10 m//s^(2) .

Two blocks of masses 2 kg and 4kg are connected through a massless inextensible string. The co-efficient of fricition between 2kg block and ground is 0.4 and the coefficient of friction between 4kg block and ground is 0.6. The forces F_(1)=10N and F_(2)=20N are applied on the blocks as shown in the figure. Calculate the frictional force between 4 kg block and ground (Assume initially the tension in the string was just before forces F_(1) and F_(2) wer applied).
