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
Find the speed of the particle at this time
p(t)=p(0)+v*t + 1/2 a t^2
= 8t i + 2.50t^2 j
v(t)= v(0) + a*t= 8i+5.00 t j
