Velocity V ms, of a moving body at time t seconds is given by V = 5t^2 -12t + 7
To find the velocity of the moving body at a given time t, substitute the value of t into the equation V = 5t^2 - 12t + 7.
For example, if you want to find the velocity at t = 2 seconds, you would substitute t = 2 into the equation:
V = 5(2)^2 - 12(2) + 7
Now, solve the equation:
V = 5(4) - 24 + 7
= 20 - 24 + 7
= -4 + 7
= 3
Therefore, the velocity of the moving body at t = 2 seconds is 3 m/s.
You can find the velocity at any other time t by following the same process. Just substitute the desired value of t into the equation and solve for V.
