- John walks 1.80 km north, then turns right and walks 1.20 km east. His speed is 1.40 m/s during the entire stroll.The other day, while riding my bike, I was forced to stop quickly to avoid a squirrel in the middle of the road 60 feet ahead. I decelerated at a constant rate of 15 ft/sec², skidding all the way. One second into the slide, my trip computer said I was going 27 ft/sec. How far did I skid before stopping? Did I avoid hitting the squirrel? Round to the nearest tenthIf you drive from Santa Cruz to San Jose, and back to the same place you started in 1.5 hours. What is your average velocity in m/s? Assume that the odometer in your car changes by 60 miles in your round trip.
- What is the magnitude of your average velocity (in m/s)?At an air show, a jet plane has velocity components vx =695km/h and vy =415km/h at time 4.35 s and vx =938km/h and vy =365km/h at time 7.52 s. Please answer A,B,C,D Thank you.Solve the problem. A rocket is propelled upward from a height of 112 feet at an initial velocity of 96 ft./s period after how many seconds does the rocket hit the ground?
- Chapter 02, Problem 10 In reaching her destination, a backpacker walks with an average velocity of 1.26 m/s, due west. This average velocity results, because she hikes for 6.62 km with an average velocity of 2.54 m/s due west, turns around, and hikes with an average velocity of 0.381 m/s due east. How far east did she walk (in kilometers)? dw VE West East dɛ Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show WorkA police car is located 60 feet to the side of a straight road. A red car is driving along the road in the direction of the police car and is 180 feet up the road from the location of the police car.
