Program Explanation Given information: The initial velocity of the car is v 0 = 88 ft/s and the final velocity of the car is v = 0 ft/s and the car skids 176 ft after its breaks. Concept used: The differential equation d y d x = f ( x ) g ( y ) can be calculated with the help of separating the variables as, ∫ d y g ( y ) = ∫ f ( x ) d x Calculation: Consider x ( t ) as the position function. The function v ( t ) represents the velocity function. The velocity function can be written as, v ( t ) = v 0 + a t Here, a is the acceleration and v 0 is the initial velocity. The deceleration is the negative value of acceleration. Therefore, the velocity function can be written as, v ( t ) = v 0 − a t ....... (1) The initial velocity of the car is v 0 = 88 ft/s and the final velocity of the car is v = 0 ft/s and the car skids 176 ft after its breaks. Now substitute 88 for v 0 and 0 for v ( t ) in equation (1) to obtain the value of a t . 0 = 88 − a t a t = 88 The position function can be written as, x ( t ) = 1 2 a t 2 + v 0 t

A tube 1.30 m long is closed at one end. A stretched wire is placed near the open end. The wire is 0.357 m long and has a mass of 9.50 g. It is fixed at both ends and oscillates in its fundamental mode. By resonance, it sets the air column in the tube into oscillation at that column's fundamental frequency. Assume that the speed of sound in air is 343 m/s, find (a) that frequency and (b) the tension in the wire. (a) Number i 66.0 (b) Number i Units Hz Units

2. The flight of a model rocket can be modeled as follows. During the first 0.15 s the rocket is propelled upward by the rocket engine with a force of 16 N. The rocket then flies up while slowing down under the force of gravity. After it reaches the apex, the rocket starts to fall back down. When its downward velocity reaches 20 m/s, a parachute opens (assumed to open instantly), and the rocket continues to drop at a constant speed of 20 m/s until it hits the ground. Write a program that calculates and plots the speed and altitude of the rocket as a function of time during the flight.

A ball is thrown from the top of one building toward a tall building 50 ft away. The initial velocity of the ball is 20 ft/s at 400 above the horizontal. How far above or below its original level will the ball strike the opposite wall?
