(a) Find the vector position of the particle at any time t (where t is measured in seconds). 8 ti + .5 t 2 j ) m (b) Find the velocity of the particle at any time t. 8 1 + 1 t j) m/s (c) Find the coordinates of the particle at t = 7.00 s. X = 15 m y = 15 m (d) Find the speed of the particle at t = 7.00 s. 7 X Remember that the constant acceleration equations are used separately for the x direction and for the y direction. m Need Help?
