Question

If velocity vector of an object is 10 units along x axis at t = 0 and 10 units along y axis at t = 5 sec,
write its initial
and final velocity in vector form (in terms of ij and k).
a. Subtract initial velocity from final velocity to find change in velocity in vector form.
b. Find the magnitude of change in velocity.
c.Divide the magnitude of change in velocity to find magnitude of acceleration.
