Refer `Q.139`. The average acceleration of the body from `t = 0` to `t = 15 s` is.

Find the modulus of average acceleration (in m/s2) of the block from time t = 2 sec to t = 4 sec.

Acceleration of a particle is given by a= 3t^(2)+2t +1 Where t is time . Find (i) its velocity at time t assuming velocity to be 10 m/s at t = 0. (ii) its position at time t assuming that the particle is at origin at t = 0. (iii) What is the average speed of the particle in the duration t = 0 to t = 1s? (iv) What is the average acceleration of the particle in the duration t = 0 to t = 1s?
