A particle initially located at the origin has an acceleration of a→ = 1.00ȷ^m/s2 and an initial velocity of v→i = 9.00 i^m/s. (a) Find the vector position of the particle at any time t (where t is measured in seconds). ( ti^+ t2 j^)m (b) Find the velocity of the particle at any time t. i^+ tj^)m/s (c) Find the coordinates of the particle at t = 3.00 s. x = m y = m (d) Find the speed of the particle at t = 3.00 s. m/s
