Question

at t=0, an object starts to move from rest and moves in the xy plane with the acceleration a=(4.0i+3.0j)m/s^2. determine a) the x and y components of velocity b) the speed of the particle and c) the position of the particle , all as a function of time. d) evaluate all above at t=2.os

Answer 1

a = 4i+3j
v = 4t i + 3t j
speed = |v| = 5t
r = 2t^2 i + 3/2 t^2 j
