Create a program that plots the trajectory, from the initial height
to the ground, of a projectile accelerating both in the horizontal
and vertical directions.

PROBLEM 4: In your physics class, projectile motion has two components: constant-velocity motion in the horizontal direction and free-fall motion in the vertical direction. However, in reality, the horizontal motion has acceleration due to air resistance, wind, and other factors. The goal of this problem is to visualize the trajectory of a projectile...

1. A projectile is fired straight upward at 170 m/s near the surface of Planet X, which has no atmosphere and where the acceleration due to gravity is g = 5 m/s2. (a) What is the acceleration of the projectile halfway to the top of its trajectory? [1] (b) Is the projectile in equilibrium at the top of its trajectory? Explain. [1.5] (c) How fast is it moving at the instant it reaches the top of its trajectory? (0.5] (d)...

The image shows the trajectory of baseball, with four labelled positions A through D. Positions A and C are at the same height, position B is at the highest point of the trajectory, and position D is shortly before the player catches the ball. Neglect air resistance for this problem. Which one of the following statements is true? The ball has maximum acceleration at point D. The ball has zero acceleration at point B. The horizontal component of the velocity...

1. A cannon fires a cannonball at an angle of 30° above horizontal. The initial velocity of the cannonball is 40 m/s. Assume the coordinate system in which x is horizontal and y is vertical. (a) What is the x-component of the initial velocity? '40 % cos ao (b) What is the y-component of the initial velocity? (c) Gravity causes a constant acceleration of 9.81 m/s. In what direction is this acceleration? (d) What affect will this acceleration have on...

A rocket is fired at an angle from the top of a tower of height h0 = 40.0 m. Because of the design of the engines, its position coordinates are of the form x(t) = A + B t2 and y(t) = C + D t3, where A, B, C and D are constants. The acceleration of the rocket 3.00 s after firing is a = (7.00 i + 5.00 j) m/s2. Take the origin of coordinates to be at...
