Displacement of a particle is given by the expression `x = 3 t ^ { 2 } + 7 t - 9`, where x is in meter and t is in seconds. What is acceleration ?

The displacement of a particle is represented by the equation, s=3 t^3 =7 t^2 +4 t+8 where (s) is in metres and (t) in seconds . The acceleration of the particle at t=1 s is.

The displacement of a particle moving in a straight line, is given by s = 2t^2 + 2t + 4 where s is in metres and t in seconds. The acceleration of the particle is.

The displacment of a particle is represented by the following equation : s=3t^(3)+7t^(2)+5t+8 where s is in metre and t in second. The acceleration of the particle at t=1:-

The displacment of a particle is represented by the following equation : s=3t^(3)+7t^(2)+4t+8 where s is in metre and t in second. The acceleration of the particle at t=1:-

The displacement of a particle moving in a straight line is given by x=2t^2+t+5 where x is expressed in metre and t in second. The acceleration at t = 2 s is

The x and y coordiates of a particle at any time t are given by x = 7t + 14 t^(2) and y = 5t, where x and y are in metre and t is in second. The acceleration of the particle at t = 5 s is

The displacement of a particle is given by x = (t-2)^2 where x is in metres and t in seconds. The distance covered by the particle in first 4 seconds is

A particle is moving in a straight line. Its displacement at any instant t is given by x = 10 t+ 15 t^(3) , where x is in meters and t is in seconds. Find (i) the average acceleration in the intervasl t = 0 to t = 2s and (ii) instantaneous acceleration at t = 2 s.
