Tony Stark is standing beside Thor who is standing on the top of Stark Tower (425 m) his hammer has a mass equal to 300 billion elephants (call it 4.5*1015 kg) Tony and Thor drop at the same time. Tony drops his lucky penny. Thor his hammer. How fast (in m/s) will Tony’s lucky penny be traveling just before it strikes the ground, assuming nothing stops it?

A fast train bump into a slow train going the same direction, and they get coupled together. The fast train was initially going 6.93 meters per second and the slow train 3.1 meters per second. What is the final speed (in meters per second) once the two are coupled?
A car travels 20kph faster than a truck. The car covers 350km in two hours less than the time it takes the truck to travel the same distance. What is the speed of the car? How about the truck?
A rocket is being launched. After a while, it rises at a constant velocity of 50 miles per second. An observer is standing 35 miles from the launching site. How fast is the distance between the rocket and the observer changing when the rocket is at a height of 12 miles? Present your answer as an approximation, accurate up to three or more decimals.
1. Andrew and Kevin decide to try out the physics ideas that they are learning and take their baseball pitching machine and a baseball to a 96 feet tall local building. Based on what they have learned the height, s(t), of a baseball, thrown straight up with an initial speed of 80 feet per second from a rooftop 96 feet high is s(t)=-16t^2+80t+96 where t is the elapsed time that the baseball is in the air. The baseball that is pitched miss the rooftop on their way down and eventually strike the ground. a) What is the average velocity of a baseball from t=0 to t=2 seconds? b) What is the velocity of the baseball 2 seconds after it is thrown? c) After how many seconds will the velocity of the baseball reach zero? d) What is the velocity of the baseball t seconds after it is thrown? e) What is the velocity of the baseball as it passes the roof top on the way down?
That's what I thought too! But the answer choices it gave were 8 m/s, 4 m/s, 2 m/s, and 6 m/s so I'm confused. I went with 8 and it was wrong.

I was able to understand the attached problem and have the answer now for mu. So the equation I have is v=150e-6.0788 x My question, then, is how do we find the TIME to slow the sled to 15 mi/hr ? The answer is supposed to be 35.533 seconds, but I don't know how to get that. Thanks!
