What is the magnitude of force on a particle of mass 20kg with a displacement function of S = 12.5t + t2

A force F = 5i + 3j act on a body and changes its position from P1(4,5) to P2 (-3, 6) in a plane. Find the workdone on the body if the force is in Newton and displacement in meter.

A particle moves with a uniform velocity function V = 4 ¾ - 3t. calculate the maximum distance traveled by the particle before stopping.

A particle moves with a uniform acceleration of 5m/s^2 in 10 seconds. what is the average distance covered in the last one second

a particle moves with a displacement function S = 20t - 1/2t^2. calculate the time taken for the particle to come to rest.

Calculat the discharge if the diameter of the pipe is 30 mm with the velocity is 15 m/s

For a given motion, the relationship between time t and distance x is found out to be t=ax^2+bx, where a and b are constants. Considering v as velocity, the retardation will be given by,
