Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.16 m, and observe that it hits the floor 0.199 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 54.5 m/s^2 54.5 m/s^2 174.6 m/s^2 109.1 m/s^2

A rocket begins at rest in outer space. Its thrusters ignite and it accelerates at 7 m/s2 for 41 s. After that, the thrusters shut off and the rocket coasts for an additional 84 s. How far does the rocket travel during both of these time periods combined, in m? (Please answer to the fourth decimal place - i.e 14.3225)
Any assistance with this physics problem would be great!
The Hulk, on the 75th story of Stark Tower (225 m off the ground), sees Tony drop his penny. He catches the penny and throws it back to Tony. What is the minimum speed necessary for Hulk's throw in order for the penny to reach Tony? (Note: nobody bothers trying to get Mjolnir back to Thor. He's on his own.)
You go to the roof of the twelve story building and look over the edge to the reflecting pool 170 feet below. You drop your book over the edge at the same instant that azmira chucks his book straight down at 48 feet per second . By how many seconds does his book into the water?
The average person passes out at an acceleration of 7g (that is, seven times the gravitational acceleration on Earth). Suppose a car is designed to accelerate at this rate. How much time (in seconds) would be required for the car to accelerate from rest to 59.9 miles per hour? (The car would need rocket boosters!)
OK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 7.42 m/s^2. When you drop a ball from a height of 1.74 m, it hits the floor 0.254 s later. What is the value of g for the alien world below you? 1. 63.8 m/s^2 55.2 m/s^2 3 79.1 m/s^2 4 46.5 m/s^2

The Empire State building in New York City is 381 m tall. If a penny were dropped from rest at the height, how many seconds would it take to strike the street below? Air resistance would make a significant difference in the real world case, but ignore air resistance for now.
A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 46 ft/s. Its height in feet after t seconds is given by y = 46t – 21t2. A. Find the average velocity for the time period beginning when t=2 and lasting .01 s: .005 s: .002 s: .001 s: NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator. Estimate the instanteneous velocity when t=2.
Moving sidewalks are installed every other 50 meters along the entire stretch of an airport walkway. These sidewalks move at a constant speed of 1 m/s. A lady passenger takes one of the sidewalks to go from one point to the next. If the passenger decides to go back using the same sidewalk at 1 m/s, how long will it take to reach her point of origin?
I've been trying to figure out the last three steps for an hour now, but I can't seem to figure out the correct answers.
