Solving Force Needed for Moving Body from Rest at 5m/s for 15m in 2s

[-Physician]

Homework Statement

What force is it needed to move a body from rest at velocity of 5m/s on distance 15m, for time of 2s. Assume no friction.

Homework Equations

$F_{net}=ma$

The Attempt at a Solution

Can I solve this problem without the mass of the body, if yes, what formula is needed? thanks!

If you want an actual number for the force, then you need mass. Think about pushing a truck on ice (zero friction) versus pushing a small car. Wouldn't it require more force for the larger object to attain the same speed?
