A 1200 kg car goes from 15 m/s to 30 m/s in 10 s. What is the average force acting upon it? Remember your units. F = ma a = final velocity - initial velocity time Which one of Newton's laws of motion applies to the following situation? "A stationary chair in a room" Which one of Newton's laws of motion applies to the following situation? "A bowling ball and a baseball shot from a cannon are moving with the same velocity but the bowling ball needs a greater force to stop it than the force needed to stop the baseball. Which one of Newton's laws of motion applies to the following situation? "As a person swims, he/she pushes the water in the backward direction with his/her hands and the water pushes the person in the forward direction with an equal force Re-write the sentence below with the missing word. According to Newton's second law of motion, acceleration is equal toAnswer divided by mass. Re-write the sentence below with the missing word.

2. Which one of Newton's laws of motion applies to the following situation?
"A stationary chair in a room"

Actually, all three.
The First: because all forces (gravitational and reaction) are compensated, the chair
resides in rest.
The Second: πΉ = ππ, πΉ = 0, π = 0.
The Third: the force which acts from the floor to the chair and the force that acts from the
chair to the floor have the same magn...
