A roller coaster is moving at 35 m/s at the bottom of a hill. Four seconds later it reaches the top of the hill moving at 10 m/s. What was the acceleration of the coaster? 10 m/s minus 35 m/s = -25 m/s divided by 4 seconds = -6.25 m/s/s (deceleration)
A swimmer speeds up from 0.9 m/s to 1.4 m/s during the last 25 seconds of a race. What is the acceleration of the swimmer? 1.4 m/s minus .9 m/s = .5 m/s divided by 25 seconds = .02 m/s/s
If a speeding train hits the brakes and it takes the train 25 seconds to go from 50 m/s to 15 m/s what was the acceleration? 15 m/s minus 50 m/s = -35 m/s divided by 25 seconds = -1.4 m/s/s (deceleration)

A student quickly pulls a paper from underneath an inverted bottle. The bottle will stay in the same spot, but on the table itself because it has enough inertia (mass) to overcome the force of the paper moving underneath it. An object at rest will stay at rest unless acted on by an unbalanced (net) force.
![Page 23: State Newton’s First Law of Motion State Newton’s Second Law of Motion Describe the motion of an object being acted upon by balanced forces.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649ccc5503460f94995d91/html5/thumbnails/23.jpg)
Two of the forces involved are gravity (weight) & the force of the pullMass plays a role in this way: mass gives the bottle enough inertia to overcome the paper’s force

10 N 7 N
What direction will the block move & why? To the right…net force is 10N minus 7N = 3NWhat will the block’s acceleration be? Force divided by mass = accel so… 3N divided by 10 Kg = .3 m/s/s
10 Kg
Describe the motion of an object that is being acted on by unbalanced forces. Be sure to use the term “net force”. No net force so no movement
