I wonder just how much Uber know about the vast subject called calculus. Lets see who can get these right:
1: Jack is driving a car on a highway at 100mph. Jill walks onto the highway 10 miles ahead of Jack. Jack sees this and at first decides to just run Jill over, so he accelerates and attains a speed of 125mph in 4 seconds. Then his humanity kicks in and he slams on the brake, constantly decelerating so that he has a speed of 80 mph, 4 seconds later. Will Jill be splattered across Jack's car?
2: Sideburns has been preparing his revenge on Person L, and finally decides to carry it out. He finds Person L entering a small apartment on the 5th floor of an apartment building. Sideburns takes the gas can he has been holding and covers the door to the apartment in gas. After that, he lights it on fire. The fire trucks soon arrive, and swing their 25ft crane to the apartment that Person L is in. Person L climbs out the window and onto the crane. However, the truck's brakes fail and it begins moving forward at a speed of 10 feet per second due to the combined weight of the crane and its passengers.
A) How fast is Person L falling when he is 7ft above the ground?
B) If Person L had a woman with him, who also crawled onto the crane and added 4 feet per second to the truck's initial speed, how fast are Person L and the woman going when they are 7ft above the ground?
3: In 20 years, Carl is killed by a heart attack. His family decides to pool their funds and pay for the freezing of his body in hopes that he can be revived some day. However, due to certain circumstances, his -100° body was taken out of the freezer and put into a 70° room. Three hours later, his body was 60°.
A) What was his body's temperature after an hour?
B) When did his body's temperature reach 0°?
