1. A constant 5 N horizontal force hits a stationary 2 kg ball. What is its speed after going 10m?

2. A 2 kg mass is pulled 4m across a frictionless horizontal surface by a 25 N force. If the mass begins from rest, what is its speed after traveling the 4 m?

3. A 5N force causes a 2 kg body to change speed from 4 m/s to 6 m/s. Over what distance does this force act?

4. A 1500 kg motorcycle moving at 20 m/s is stopped by an 800 N frictionless force. How far does it take the bike to stop?
