A particle initially located at the origin has an acceleration of a= 5.00J^ m/s^2 and an initial velocity of v0= 8.00I^ m/s

A) Find the vector position at any time t where t is measured in seconds.

Find the vector velocity at any time t.

b) Find the coordinates of the particle at t=4.00s

x=

y=

Find the speed of the particle at this time
