Question

The x and y coordinates of a particle at any time t are given by x = 2 t + 4 t 2 and y = 5 t , where x and y are in metre and t in second. The acceleration of the particle at t = 5 s is, 40 m s - 2, 20 m s - 2, 8 m s - 2, zero

For x component v x = d x d t = 2 + 8 t m s - 1 a x = d v x d t = 8 m s - 2 For y component v y = d y d t = 5 m s - 1 a y = d v y d t = 0
