A horse has to pull a cart harder in the initial stange of his motion . Why ?

"A horse has to pull a cart harder during the first few metres of its motion than later on ". Why ?

"A horse has to apply more force to start a cart than to keep it moving ". Why?

Consider the following A and B, and identify the correct choice in the given answers. A) For a body resting on a rough horizontal table, it is easier to pull at angle that push at the same angle to cause motion B) A body sliding down a rough inclined plane of inclination equal to angle of friction has nonzero acceleration

Explain why a horse cannot pull a cart and run in empty space

(A)A horse cannot pull cart and run in empty space ( R) : The mutual action- reaction forces between the horse and cart get cancelled

Explain why (a) A horse cannot pull a cart and run in empty space. (b) Passengers are thrown forward from their seats when a speeding bus stops suddenly. (c ) A cricketer moves his hands backwards when holding a catch.

A man of mass 80 kg is riding on a small cart of mass 40 kg which is rolling along a level floor at a speed 2 m/s . He is running on the cart , so that his velocity relative to the cart is 3 m/s in the direction opposite to the motion of cart . What is the speed of the centre of the mass of the system ?

A particle has an initial velocity of 9m//s due east and a constant acceleration of 2m//s^(2) due west. The distance coverd by the particle in the fifth second of its motion is :

A mass of 2kg is suspended with thread AB (figure) Thread CD of the same type is attached to the other end of 2kg mass. Lower thread is pulled gradually, harder and harder in the downward direction so as to apply force on AB . which of the threads will break and why?
