If displacement is depend on time such that x = 2t –2 then find out average speed upt to 4 sec

If velocity is depend on time such that v = 4 – 2t. Find out distance travelled by particle from 1 to 3 sec

Position time graph is given find average speed in time t=0 and t=15 sec is

Position time graph is given find average speed in time t=0 and t=15 sec is

Position time graph is given find average speed in time t=0 and t=15 sec is

If displacement x at time t is x = sqrt(1+ t^(2)) , then acceleration is

The displacement (x) of particle depends on time (t) as x = alpha t^(2) - beta t^(3) .

The displacement of a body along the x-axis depends on time as sqrt(x)=t+2 , then the velocity of body

For a particle moving along a straight line, the displacement x depends on time t as x = alpha t^(3) +beta t^(2) +gamma t +delta . The ratio of its initial acceleration to its initial velocity depends
