A dragster makes a pass down a track in exactly 8.3 seconds.
At the end of this pass, its velocity is exactly 50 meters per second.
Its average acceleration during this pass is _______ meters / second2
Your answer should be accurate to the nearest 0.1 meter/second2
Hint: You do not need to know the length of the track to solve this problem.

(20 points) Take a ball, with a fan attached to it pointing downward, with a total mass (ball + fan) of 1/5 Kg. This whole arrangement is thrown vertically upward from the edge of a building 50 meters high with an initial velocity of 30 meters/second, with the fan turned on The fan exerts an upward force of (1-e-3) Kg...
Differential Equation problem
We know that a force of 2.8 Newtons is required to stretch a certain spring 0.7 meters beyond its natural length. A 1.44-kg mass is attached to this spring and allowed to come to equilibrium. The mass-spring system is then set in motion by applying a push in the upward direction that gives the mass an initial velocity of 1.04 meters per second. Let y(t) represent the displacement of the mass above the equilibrium position t seconds...
Assignment 9 If you run around a half-mile track twice in 20 minutes a. What is the total distance traveled? b. What is the speed in mi/hr (show work)? c. What is the total displacement? d. What is the velocity in mi/hr? You travel east 2 miles and then turn to the north and walk another 3 miles. What is your displacement (show work, make sure to show the direction as well)? You travel 6 miles at 40 degrees. How...

Problem Report 2a: The Diving Problem (e) Find the average velocity of the diver for each of the following time intervals Problem Report 2a: The Diving Problem A diver leaps from a 3 meter springboand. His feet leave the board at time 0 seconds, he reaches his maximum height of 5 meters at 1 second, and enters the water at 3 seconds. Once in the water, the diver coasts to the bottom of the pool (depth & meters), toaches bottom...

A second rock is thrown straight upward with a speed 6.000 m/s, If this rock takes 1.828 s to fall to the ground, from what height H was it released? Express your answer in meters to three significant figures A rock thrown with speed 12.0 m/s and launch angle 30.0 (above the horizontal) travels a horizontal...
1. John (who is 95 kg) drives his car over an absurdly large half-circle speedbump with a radius of 5 meters. Given that his normal weight is 930 N and his apparent weight at the top of the speed-bump was 246 N, how fast did he drive over the speed bump? 2. When working in circular motion problems, what do we define as always being the positive direction? 3. When in circular motion, the net force points in what direction?...
**Only [Harder] Question** Problem 2. Consider a firm that has a cost function of c(y) = 5y 2 + 50, 000. In other words, this is a firm with a fixed cost of $50,000 (which might be something like the cost of rent on the firm’s building, which they have to pay whether they produce any output or not) and a variable cost of $5Y 2 , (which we’ll think of as the cost of the labor and machinery necessary...
