Velocity V ms, of a moving body at time t seconds is given by V = 5t2 -12t + 7
To find the velocity of the moving body at a given time, t, we can substitute the value of t into the equation V = 5t^2 - 12t + 7.
For example, if the time is t = 2 seconds, we can find the velocity by substituting t = 2 into the equation:
V = 5(2^2) - 12(2) + 7
= 5(4) - 24 + 7
= 20 - 24 + 7
= 3
Therefore, at t = 2 seconds, the velocity of the moving body is 3 m/s.
