Write GIVEN FORMULA AND SOLUTION

PROBLEM SOLVING: 1. 2. A 20.0 kg object that can move freely is subjected to a resultant force of 45.0 N in the - x direction. Find the acceleration of the body. 2. 3. A boat has a mass of 6800kg. Its engines generate a drive force of 4100 N due to west. while exerts a force of 800 N east and the water exerts a resistive force of 1200 N due cast. What is the magnitude of the boat's acceleration? 3. Find the weight on Earth on a body whose mass is 200g. 4. Suppose a person walk 80 m east and then 50 m west. What is the person's average velocity? 5. In 5 s a truck increases its speed from 50 km/h to 70 km/h while a car goes from rest to 20 km/h. Which undergoes greater acceleration? What it its acceleration
