You throw a ball toward a wall at speed v0 = 25.0 m/s and at angle θ0 = 40.0 ◦ above the horizontal (figure below). The wall is distance d = 22.0 m from the release point of the ball. Assume no air resistance. A. How far above the release point h does the ball hit the wall? Start your argument from the basic equations of motion into the horizontal and vertical directions. B. What is the horizontal component of...

An object is moving with constant non-zero velocity in the +x axis. The position versus time graph of this object is a parabolic curve. a hyperbolic curve. a vertical straight line. a straight line making an angle with the time axis. a horizontal straight line. Car A is traveling at 22.0 m/s and car B at 29.0 m/s. Car A is 300 m behind car B when...

An object in free-fall accelerates downward at 9.8m/s^2 .However, when the object is confined to slide (or roll) frictionlessly down an inclined plane, this acceleration is a function of the angle that the inclined plane makes with the horizontal. Use this result to find the time it takes something to descend a vertical distance along a frictionless plane inclined at an angle above the horizontal

2. A baseball thrown from the outfield, a golf ball, or a thrown football, all will follow a trajectory (path) that has horizontal as well as vertical displacement components. If we neglect the air friction on the ball, the path will be a perfect parabolic trajectory. The equations for the displacement of the ball are: Take gravity g as 9.81 meters per second, and the initial velocity, Vo, equal to 35 meters/second. Use Excel to show the ball trajectory for...

1. [25 points) Idealized frictionless free fall of an object that is dropped from being at rest at i = 0. For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Consider the following experiment. A rock with a mass of m= 2 kg is dropped at the time t = 0 from a height of 140 m above ground. Assume that the rock is simply dropped...
