If a driver is initially going 24.9m/s to the right and then slams
on the brakes to accelerate at a magnitude of 3.3m/s/s until
she comes to a complete stop. If she started applying her
brakes at a position of 2m from zero, then where is her final
position from zero?
If a driver is initially going 35.5m/s to the left and then slams on the brakes to accelerate at a magnitude of 3.8m/s/s until she comes to a complete stop. If she started applying her brakes at a position of 102m from zero, then where is her final position from zero?
From the top of a cliff, a person throws a stone straight downward. The initial speed of the stone just after leaving the person's hand is 9.9 m/s.
(a) What is the acceleration (magnitude and direction) of the stone while it moves downward, after leaving the person's hand? Also, is the stone's speed increasing or decreasing?
(b) After 0.48 s, how far beneath the top of the cliff is the stone? (Give just the distance fallen, that is, a magnitude.)

- A 440g beanbag slides up a cornhole board (if you’ve never played cornhole before, the board is basically a ramp). The board is tilted 10.◦ from the hori- zontal. The beanbag initially is moving with a speed of 1.21 m/s directly up the ramp. It stops at a displacement 0.35m from where it was initially, and then slides back down 1. How does the magnitude of the acceleration of the bean bag on the wayup compare to the acceleration of the beanbag on the way down? Explainyour reasoning.2. What is the coefficient of friction between the bean bag and the ramp?3. What is the bean bag’s speed when it reaches its initial starting point onits way down?arrow_forwardAssuming that a car traveling to the South (+y direction) begins to slow down as it approaches a traffic light. What happens to the acceleration?arrow_forwardA freight train is coasting downhill on a slightly inclined railroad. At the moment when the train’s speed is 4.5 m/s, the engine is engaged. The train immediately begins to experience constant acceleration, such that it slows in its motion, stops for an instant (12.5 s after the engine is engaged), and begins to move in the opposite direction (uphill). Analyze the motion from the moment when the engine is turned on 1. How far does the train travel from the moment the engine is engaged until it reaches a momentary stop? 2. How long will it take the train to return to its position when the engine was engaged? 3. What is the speed of the train when it returns to its position when the engine was engaged? And 4.
