5. The driver of a car travelling 75.0 km/hr suddenly sees road construction up ahead. She takes 2.30 s to begin applying the brakes. The car slows down at a constant rate of 10.0 km/br's for until she comes to a stop. a. Draw a picture showing the various intervals of the car's motion and accelerations, b. Calculate the average acceleration of the car after the driver applies the brake c. What is the total distance the car travelled from...

2. For each of the following motions draw a motion diagram, a position-vs-time graph, and a velocity-vs-time graph. a. A car starts from rest, steadily speeds up to 40 mph in 15s, moves at a constant speed for 30s, b. then comes to a halt in 5s A rock is dropped from a bridge and steadily speeds up as it falls. It is moving at 30 m/s when it hits the ground 3s later. Think carefully about the signs.

You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop? A rock is tossed straight up with...

1. Draw a correctly labeled motion diagram for each of the following scenarios. Make sure you include both velocity and acceleration vectors a. A car travels along a straight, flat road at a steady speed. b. A truck slows down and comes to a stop as it approaches a red traffic light. c. A train accelerates as it leaves the train station and then keeps moving at a constant speed. d. A bungee jumper jumps from a high bridge. Initially...

When the drivers pass each other, the driver of the red car is
to toss a package of contraband to the other driver. To catch the
toss on video, one of the cameras must be set up near the point
where the toss will be made. When “action” is yelled out on the
set, the initial separation between the drivers will be 200 m, the
red car will accelerate from rest at a constant 6.12
m/s2, starting at xr =...
