A object is throw up with a speed of 25m/s. suppose that the gravity is 10m/s^2. Define the position and the velocity of the particle for the following times: 1second, 4second and 10second
Y(t) = 25 t - 5 t^2
V(t) = 25 - 10 t
Jyst plug in the different times t and compute the corresponding values of y (position) and V (velocity).
