[" If displacement of a body "s=(200+-5)m" and time taken by it "t=(20t],[0.2" ) "s" ,then find the percentage error in the calculation of velocity."]

If displacement of a body s = (200 pm 5) m and time taken by it t = (20 pm 0.2) s, then find the percentage error in the calculation of velocity.

Time taken by a body in (20 +-0.2) second in undergoing a displacement of (200 +-5) m. Calculate the percentage error in calculation of velcoity.

The displacement s of a particle at time t is is given by s=2 t^3 - 4 t^2 -5t. Then find the velocity at t=2 sec

The displacement of a body at any time t after starting is given by s=15t-0.4t^2 . Find the time when the velocity of the body will be 7ms^-1 .

The displacement of a body at any time t after starting is given by s=15t-0.4t^2 . Find the time when the velocity of the body will be 7ms^-1 .

If displacement S at time t is S=10t-5t^(2) , then velocity at time t is

A body cover 20 m in 2 s and another 20 m in next 4s. Arrange the following steps in sequential order to find th average velocity of the body . (A) Find the displacements of the body in first 2s and next 4 s from the given data. (B) find the displacements of the body . (C) find the total time taken by the body to complete the total displacement . (D) Use the formula, average velocity = ("total displacement")/(" Total time taken")

The displacement of a particle at time t is given by s= 2 t^3 - 5 t^2 + 4t -3. Find the time when the acceleration is 14 ft/ sec^2 , find the velocity and the displacement at that time.
