Which formula should I use?
A force of 17N is applied to a 6KG block which is at rest. Find:
A] Acceleration
B] Velocity
C] Distance After 9 seconds.
I solved A with the formula Force divided by Mass. [a=F/m]
17/6=2.83 m/s2
Solved B with the formula: Initial Velocity plus Acceleration times Time [Vf=Vi+a(t)]
0 + 2.83(9) = 25.47m/s
Now, for the distance (c) i have two formulas. the first one is:
Distance = Velocity * Time
and
Distance = Initial Velocity (time) + 1/2 a (time)2
Which formula is the right one to use?

you should use:
D= initial velocity*time + 1/2 a*t^2
the first formula is only for constant velocity which means a=0
