A 8.9 kg block initially at rest is pulled to the right along a horizontal, frictionless surface by a constant, horizontal force of 12.1 N.

Question

Find the speed of the block after it has moved 3.3 m.
Answer in units of m/s

Answer 1

F = m a
solve for a

then
v = 0 + a t

to get t:
d = 3.3 = (1/2) a t^2

Answer 2

F=MA>
sqrt(2AX)
distance is X
