Textbook Question
Chapter 2, Problem 35AP
The froghopper Philaenus spumarius is supposedly the best jumper in the animal kingdom. To start a jump, this insect can accelerate at 4.00 km/s2 over a distance of 2.00 mm as it straightens its specially adapted “jumping legs.” Assume the acceleration is constant. (a) Find the upward velocity with which the insect takes off. (b) In what time interval does it reach this velocity? (c) How high would the insect jump if air resistance were negligible? The actual height it reaches is about 70 cm, so air resistance must be a noticeable force on the leaping froghopper.

A jet plane comes in for a landing with a speed of 100 m/s, and its acceleration can have a maximum magnitude of 5.00 m/s^2 as it comes to rest, from the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest?
At a football tryout, a player runs a 40-yard dash in t2 = 5.00 seconds. If the reaches his maximum speed at the 15-yard mark L1 with a constant acceleration and then maintains that speed for the remainder of the run, determine his acceleration over the first 15 yards, his maximum speed, and the time duration of the acceleration.
Given the following acceleration function of an object moving along a line, find the position function with the given initial velocity and position.
