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!

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.

Greg drew a diagram to compare two of the fundamental forces. which labels belong in the areas marked x, y and z? gravitational force electromagnetic force x. attractive y repulsive z: infinite range x: infinite range y attractive z. repulsive x. always attractive y: infinite range z: attractive or repulsive x. attractive or repulsive y infinite range z: always attractive

What is friction? how does it affect the motion of an object?
