Karen is driving 65 km / h [E30S ] when suddenly she turns and is travelling at 45km / h S50E . If this takes a total of 6.0 seconds , what is Karen's acceleration during the turn?

3. The blue F1 Ford truck is travelling at 5 mph as it strikes the black SUV which then strikes the red vW Bug. Assuming all vehicles are manual transmission and in neutral (so we can make a valid assumption of ignoring friction), determine post-impact velocity of each vehicle. COR is 0.7. 3500 Ib 4100 Ib 2200 Ib

15. Abby is chasing Bradley due north along Warden Avenue at a speed of 7 m/s. She is 47 meters south of the Tim Hortons while Bradley makes a turn to run westward at a speed of 9 m/s. What is the minimal distance between them and how many seconds after Bradley makes a turn would it happen?

3. A car travels along the three legs of an equilateral triangle. The speed for the three legs is as follows: 60 mph, 30 mph, and 40 mph. Calculate the average speed for the trip. с. 40тph d. 50mph

5. A supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 100 m above the glacier at a speed of 150 m/s. How far short of the target should it drop the package?

3. Pilots of high-performance aircraft risk loss of consciousness if the undergo accelerations exceeding about 5g. For a military jet flying at 2470 km/hr (about twice the speed of sound), what is the minimum time it takes the jet to reverse its direction in a circular turn while keeping the acceleration below the 5g safety threshold?

10. A car drives to the north at constant speed. Which direction does its acceleration point? Explain.

1. A car traveling 75 km/h slows down at a constant acceleration of 0.50 m/s^2 just by “letting up on the gas.” Calculate (a) the distance the car coasts before it stops, (b) the time it takes to stop. 2.  A horse trots away from its trainer in a straight line, moving 38 m away in 9.0 s. It then turns abruptly and gallops halfway back in 1.8 s. Calculate (a) its average speed and (b) its average velocity for the entire trip, using “away from the trainer” as the positive direction. 3.  At highway speeds, a particular automobile is capable of an acceleration of about 1.8 m/s^2. At this rate, how long does it take to accelerate from 65 km/h to 120 km/h? 4. In coming to a stop, a car leaves skid marks 65 m long on the highway. Assuming a deceleration of 4.00 m/s^2, estimate the speed of the car just before breaking. 5. A baseball is hit almost straight up into the air with a speed of 25 m/s. Estimate (a) how high it goes, (b) how long it is in the air.

A stone is dropped from rest near the surface of moon. The velocity of the stone after 3 seconds is [Given data : acceleration due to gravity of moon, 9moon = 1.6m/s2,acceleration due to gravity of earth, gearth = 9.8 m/s²] O a. +29.4m/s O b. -4.8m/s O c. -29.4m/s O d. +4.8m/s

1. You are driving at 8.00 m/s south. You accelerate uniformly at 1.10 m/s? north for 5.00 seconds. How fast are you going at the end of the 5.00 seconds? What is your displacement?
