The distance covered by a body along the X-axis is given by `x=2t^3 + 5t^2 + t` where ‘t’ is the time measured in ‘s’while x is in ‘m.Define average velocity and instantaneous velocity.

The distance covered by a body along the X-axis is given by x=2t^3 + 5t^2 + t where ‘t’ is the time measured in ‘s’while x is in m.If the average velocity of a particle is equal to its instantaneous velocity,what type of motion it represents?

The distance covered by a body along the X-axis is given by x=2t^3 + 5t^2 + t where ‘t’ is the time measured in ‘s’while x is in ‘m. Find the average velocity of the body in a time interval from t = 0 to t = 2s.

The position of an object moving along x-axis is given by x=a+tb^2 where a - 8.5 m, b=2.5ms^-2 and t is measured in seconds. What is its velocity at t = 0 s and t = 2.0 s? What is the average velocity between t = 2.Os and t = 4.0 s ?
