Newton's second law states that f = m x a (force is mass times acceleration). which example would have the greatest acceleration? (hint: you need to do calculations for these! ) a) a 10 kg ball thrown with a 50 newton force b) a 1 kg ball thrown with a 0.5 newton force c) a 50 kg student launched by a 100 newton catapult d) a 500 kg car accelerated by 1000 newtons from the engine a 3 kg lunch box is pushed across the lunch table. the acceleration of the lunch box is 2.0 m/s2. what was the net force applied to the lunch box? (hint: f = ma) show all your work! find the weight of a 10 kg rock. remember, acceleration due to gravity is -9.8 m/s2. (hint: w = mg) show all your work! a 3 kg lunch box is pushed across the lunch table. the acceleration of the lunch box is 2.0 m/s2. what was the net force applied to the lunch box? (hint: f = ma) show all your work!
