- A woman was transporting an open box of cupcakes to a school party. The car in front of her stopped suddenly; she applied her brakes immediately. She was wearing her seat belt and suffered no physical harm (just a great deal of embarrassment), but the cupcakes flew into the dashboard and became “smushcakes.” Explain what happened.The answer is not 0.08 kg, may you please help me with it and explain why?A 2000-kg car traveling at 21 m/s takes 44 m to stop under full braking. The same car under similar similar road conditions, traveling at 44 m/s takes m to stop under full braking.
- If your automobile runs out of fuel while you are driving the engine stops but you do not come to an abrupt stop. The concept that most explains why isFrom 1946 through 1958, Col. John Stapp headed the U.S. Air Force Aero Medical Laboratory's studies of the human body's ability to tolerate high accelerations during plane crashes. Conventional wisdom at the time indicated that a plane's negative acceleration should not exceed 180 m/s2 (18 times gravitational acceleration, or 18g). Stapp and his colleagues built a 700-kg "Gee Whiz" rocket sled, track, and stopping pistons to measure human tolerance to high acceleration. Starting in June 1949, Stapp and other live subjects rode the sled. In one of Stapp's rides, the sled started at rest and 360 m later was traveling at speed 67 m/s when its braking system was applied, stopping the sled in 6.0 m. He had demonstrated that 18g was not a limit for human deceleration. Find the time interval for Stapp and his sled to stop as their speed decreased from 67 m/s to zero.Lark Brandt won a "Worlds Fastest Smash" competition in the early 2000s. His ping pong ball achieved a speed of 112.5 km/hr. If his ping pong ball had a mass of 2.7 g and hit a wooden block with a mass of 125 g and bounced back with a speed of 45.0 km/hr, what speed (in km/hr) would the wooden block have?
- A physics student watches a 1 g object go from rest to 1 mm/s in 1 sec. What is the force that caused this motion?An investigation of an automobile crash suggests that vehicle A was moving at 52 mph toward the south and vehicle B was moving at an unknown speed toward the north, when the two cars collided, sticking together after the collision. Vehicle A weighs 1350 lbs., and vehicle B weighs 1893 lbs. If the cars did not move significantly after their collision, find the initial speed of vehicle B in mph. Answer: mph (miles per hour)In a dramatic rescue mission, Dr. Porter was up on a 15-meter-high cliffside where she saw a box of her favorite biochemistry textbooks about to be swept away by an oncoming rush of water. To save the books, she quickly realized the only way was to swing down Tarzan style and grab the books, safely landing on a low cliffside on the other side with the books in hand. If she weighs 2.5 times the mass of this box of books, how high is the lower cliffside if she ends up with 0 final velocity at the top of the lower cliffside.
- A swimmer with a mass of 75 kg dives off a raft with a mass of 500 kg. If the swimmer’s speed is 4 m/s immediately after leaving the raft, what is the speed of the raft? 0.2 m/s 0.4 m/s 0.6 m/s 0.8 m/s 1m/sWhat is the velocity of a 1750 kg car whose KE is 87x10J O 12.37 m/S 04.48 m/s 0 9.97 m/s O 7.16 m/s22. During a circus performance, John Tailor was fired from a compressed-air cannon whose barrel was 20 m long. Mr. Tailor emerged from the cannon (twice on weekdays, three times on Saturdays and Sundays) at 40 m/s. If Mr. Tailor's mass was 60 kg, what was the average force on him when he was inside the cannon's barrel?
