- Consider a dragster that, when the light turns green, accelerates uniformly from rest and completes a 372 meter race in a time of 6.61 seconds. a) During this period, what is the dragster's acceleration expressed as a multiple of the acceleration due to gravity, g? b) If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has traveled a total distance of 1.6km1.6km, which is approximately one mile?Explain how to solve the following question in words. Then, provide the complete solution based on your description above. If an object is dropped from an 80-meter-high window, its height y above the ground at time t is given by the formula y = f(t) = 80 − 4.9t^2. Find the average velocity of the object between (a) t = 1 sec and t = 1.5 sec.A driver traveling at 60 miles/hour rounds a flat curve when he sees an overturned truck on the highway at 400 feet.

Plot the results for reaction times starting from 0.50 to 5.00 seconds in 0.5 second increments. What's your comment?
- A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 26 ft/s. Its height in feet after t seconds is given by y=26t−13t^2A.

Their snowball leaves their hand 2.2m above the ground with a speed of 10.1m/s. When I dropped the baseball it was from rest. Create a expression that shows the position of each baseball as a function of time, find when the baseballs are at the same position.

How fast is she walking with respect to you? How far does your friend travel before she catches up with you? Indicate the uncertainty in your answers. Describe any assumptions that you made.In Peter Jackson's adaptation of The Two Towers, the wizard Gandalf falls from the Bridge of Khazad-dûm for a total screen time of 71 seconds. Darren wanted to calculate the maximum height the fall could have been and running the numbers concluded that it could be at most 4.94 km from the bridge to the heart of the mountain below. Is Darren's conclusion a fair estimation of the total fall distance?Be sure to:*State your claim with disagreeing with 4.94 km being a reasonable height for the fall.*Gather evidence from your choice of a combination of your own calculations and observations from the film (lord of the rings -Gandalf vs Balrog entire battle HD) *Connect your evidence to your claim by reasoning why it supports your claim. Any evidence you share should be directly linked with your reasoning to why or why not 4.94 km or 4,940 m is a reasonable estimate for the falling distance.
