- The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? i have tried so many ways to solve this and i cant please explainA Wide Reciever is running along the sideline straight towards the goal at a constant speed. When he is 27 m away from the goal line he cathces the ball, but theire is a cornerback 12 m behind him moving with a connstant speed of vc=9.0 m/s what speed should the wide reveiver have to make sure he reaches the goal line just as the cornerback reaches him.In a game of baseball, a player hits a high fly ball to the outfield.(a) Is there a point during the flight of the ball where its velocityis parallel to its acceleration? (b) Is there a point where the ball’svelocity is perpendicular to its acceleration? Explain in each case.
- KACTICE ANOTHER Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of 3.50 m/s, and the second a velocity of 4.20 m/s. (a) What is the velocity of the second runner relative to the first? m/s faster than the front runner. (b) If the front runner is 250 m from the finish line, who will win the race, assuming they run at constant velocity? O The first runner will win. O The second runner will win. (c) What distance ahead will the winner be when she crosses the finish line? m Additional Materials Reading ASK YOUR TEACHER PRACTICE ANOTHE MY NOTESA fullback preparing to carry the football starts from rest and accelerated straight ahead. He is handed the ball just before he reaches the line of scrimmage. Assume that the fullback accelerates uniformly (even during the handoff), reaching the line with a velocity of 8.00 m/s. If he rakes 1.00 s to reach the line, how far behind it did he start?The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. a) What was its initial speed (in m/s), just before the brakes were applied? b) What was its acceleration (in m/s2) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction with the sign of your answer.) I tried to solve both, but i cannot seem to get the correct answer. please explain
- 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 =…A car and a jeep are 7 km apart.
