You purchase the new Tesla Roadster and decide to take it out for a spin on theNewmarket Race Track. After getting to a top speed of 410. km/hr, suddenly atree falls down on the road blocking your path. You slam on your brakes to avoidhitting the fallen tree and thus, come to a complete stop. You were at a distanceof 30.0 m away from the tree when you hit the brakes. Assuming that theRoadster does not skid, what is the minimum deceleration needed to avoidhitting the fallen tree?
Wellington Wildcat is rushing to get to a parade in time to be the grand marshal. He’s standing in theback of a flatbed truck while McFogg the Dog races at 25 m/s towards town. Suddenly, McFogg sees atiny maple leaf in the road 55 m ahead, and, being a proud Canadian, slams on the brakes to protect thesacred totem. Since McFogg is known to ride the brakes like a real jerk, let’s assume his reaction time tohit the breaks is essentially zero.A. Can McFogg actually stop before the truck reaches the leaf? The coefficients of friction betweenrubber tires and dry concrete are: μs = 1.00, μk = 0.80. When answering this question, be sure toinclude a free-body diagram representing the truck and its stellar mascots as a single object.B. Now here’s the real serious question: Is it possible for McFogg to stop short of the leaf such thatWellington does not slip and slide into the back of the truck cab? The coefficients of friction forWellington’s shoes on the bed of the truck are: μs = 0.60, μk =…
You can accelerate and brake on your bicycle with a maximum magnitudeof the acceleration of 3 (m/s)/s. Your top speed is 12 m/s. You want to drop ofyour physics textbook at your friend who normally works with an electronictextbook version, but just called and asked you for your printed copy for theafternoon. She lives 168m up the road from you. You need 11 seconds to runout of your apartment and grab your bike, and you need another 11s to run toyour friend’s apartment door to hand her the book after stopping with your bike.How long to you need in total to bring her the book?
You stand at the top of a cliff while your friend stands on the ground below you. You drop a ball from rest and see that she catches it 1.2 s Your friend then throws the ball up to you, such that it just comes to rest in your hand. What is the speed with which your friend threw the ball?
A jeepney and a train are moving together along parallel paths at 30.0 m/s, with the jeepney adjacent to the rear of the train. The jeepney driver sees the traffic light turn red, so he accelerates at -2.50 m/s2, and then let his jeepney come to rest. The jeepney is at rest for 50.0 s, and then accelerates at 2.50 m/s2 to go back to a speed of 30.0 m/s. Assuming that the speed of the train remained constant at 30.0 m/s, how far is the jeepney from the rear of the train when the jeepney reaches a speed of 30.0 m/s?
Two people are skating on ice. The first one skates by the second witha constant velocity of 12.0 m/s. The second person, not wanting to beleft behind, begins at rest and then accelerates at a = 4.0 m/s2in thedirection of the first skater as soon as the first skater passes by. How farmust the second skater skate before she catches up with the first skater?
Speedy Sue, driving at 32.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 165 m ahead traveling at 5.30 m/s. Sue applies her brakes but can accelerate only at -1.30 m/s² because the road is wet. Will there be a collision? O Yes O No
A race car entering the curved part of the track at the Daytona 500 drops its speed from 85.0 m/s to 80.0 m/ s in 2.0 s. If the radius of the curved part of the track is 316.0 m, calculate the total acceleration of the race car at the beginning and ending of reduction of speed.
here is my problem, I need help: One simple model for a person running the 100 mm dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.1 m/sm/s in 2.64 ss , what will be his total time? Express your answer in seconds.
