Question

A body moves in a straight line along x-axis, its distance from the origin is given by the equation x = 8 t –

4 t 2

. The average velocity in the interval from t = 0 to t = 4 is:

​

Answer 1

x = equation

v = dx/dt

Formula for average Velocity

= ∫ v. dt / ∫ dt

= ∫( dx/dt). dt /dt

= ∫ dx/dt
