A particle of mass m initially at rest is acted upon by a unidirectional force ` F=F_@cos ((pi)/(2) t) .` The distance travelled by the particle when it stops first in the subsequent motion is ,

A particle of mass m, initially at rest, is acted on by a force F=F_0{1-((2t-T)/T)^2} during the interval 0lt tlt T . The velocity of the particle at the end of the interval is :

A particle of mass m initially moving with speed v.A force acts on the particle f=kx where x is the distance travelled by the particle and k is constant. Find the speed of the particle when the work done by the force equals W.

A particle of mass m initially moving with speed v.A force acts on the particle f=kx where x is the distance travelled by the particle and k is constant. Find the speed of the particle when the work done by the force equals W.

A particle of mass m , initially at rest , is acted upon by a variable force F for a brief interval of time T . It begins to move with a velocity u after the forrce stops acting . F is shown in the graph as a function of time. The curve is a semicircle.

A particle of mass 'm' and initially at rest is acted by a force F=a t. Newtons best representation of force-displacement graph is:

A particle of mass 4 kg is acted upon by steady force of 4 N.Distance travelled by the particle in 4 sec is
