The University Skydiving Club has asked you to plan a stunt for an air show. In this stunt, two skydivers will step out of opposite sides of a stationary hot air balloon 1500 meters above the ground. The second skydiver will leave the balloon 20 seconds after the first skydiver but you want them both to land on the ground at the same time. The show is planned for a day with no wind so assume that all motion is vertical. To get a rough idea of the situation, assume that a skydiver will fall with a constant acceleration of 9.80 m/s2 before the parachute opens. As soon as the parachute is opened, the skydiver falls with a constant velocity of 3.2 m/s. If the first skydiver waits 3 seconds after stepping out of the balloon before opening her parachute, how long must the second skydiver wait after leaving the balloon before opening his parachute?

A skydiver is at an altitude of 1,525 m. After 11.0 seconds of free fall, he opens his parachute and finds that the air resistance, FD, is given by the formula FD = −bv, where b is a constant and v is the velocity. If b = 100,and the mass of the skydiver is 86.0 kg, first set up differential equations for the velocity and the position, and then find the following. (Assume air resistance is negligible prior to the...

1.)You are hitting baseballs. When you toss the ball into the air, your hand is 5 feet above the ground (see figure). You hit the ball when it falls back to a height of 3.5 feet. You toss the ball with an initial velocity of 20 feet per second. The height h of the ball t seconds after leaving your hand is given by h = 5 + 20t ? 16t2. How much time will pass before you hit the...

1. Physics and astronomy student club has a recently established tradition of pumpkin drop, from the top of Wick Science Building to the "moat" below street level. Although the "experimental data" have not been made public, there have been rumors of the drop took 2.07 seconds, i.e. falling from rest with negligible air drag. Based on the rumor, how tall is the building from the "moat" to the roof? Ignore air drag or any rotation of pumpkins. Hint: You may...

Chick-fil-A is dominating the U.S. fast-food market. Whereas McDonald’s, Subway, Burger King, and Taco Bell trudge along at the top of the heap, Chick-fil-A has quietly risen from a South- east regional favorite to become the largest chicken chain and the eighth-largest quick-service food purveyor in the country. The chain sells significantly more food per restaurant than any of its competitors—twice that of Taco Bell or Wendy’s and more than three times what the KFC Colonel fries up. And it...
