Suppose an outfielder throws a baseball with an initial speed of 12 m/s in a direction 30° up from the horizontal. Use a trajectory diagram to determine the height of the peak of its trajectory in reality. I suggest using a time step of Δt = 0.2s and a scale of 1.0 m (in reality) = 2.0 cm (on diagram).   The height of the peak of its trajectory in reality is ______ m.

What horizontal distance should the professor be at when the egg is released?

A golf ball is driven with the initial conditions shown in the figure. If the wind imparts a constant horizontal deceleration of 3.9 ft/sec2, determine the values of r, r˙, r¨, θ, θ˙, and θ¨ when t = 1.18 sec. Take the r-coordinate to be measured from the origin.

H3.6.  A bullet is fired from ground level at 120 m/s in the +55° direction. The bullet hits the ground x meters away. Using the formula (y = v0yt …) and obtain the time interval the bullet travels through air.   Calculate how far from the point that it was fired the bullet will hit the ground.

A ball is launched from the ground with an initial velocity vF18.1 m/s at an angle of 39.5° above the horizontal. It hits a wall located a horizontal distance of 22.0 m from the launch point. (c) How long does it take for the ball to hit the wall? Provide your answer in seconds (s). Use 3 significant figures. Your Answer: Answer units

A rifle is aimed horizontally at a target 25m away. The bullet hits the target 1.5cm below the aiming point. What are (a) the bullet's time of flight and (b) its speed as it emerges from the rifle? Make sure you give the units for each answer.

A student standing on a cliff that is a vertical height d= 25 ft above the level ground throws a stone with velocity v0= 73 ft/s at an angle θ = 25 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position. 1).With what speed, vf in feet per second, does the stone strike the ground?  2).

A vehicle travels at a speed of 4 m/ sec along a horizontal Circular road that has a radius of 50m its speed is then increased by ú= (0.05.s) m/sec² for a short distance from S = 0, where s is in meters. Calculate the magnitude of its acceleration when it has moved s = 10m in ml sec².

ment Chapter 04, Problem 039 Your answer is partially correct. Try again. In the figure, a ball is thrown leftward from the left edge of the roof, at height h above the ground. The ball hits the ground 1.80 s later, at distanced = 26.0 m from the building and at angle 0 = 56.0° with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on videotape.) What are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball is thrown (positive angle for above horizontal, negative for below)?

A jeep travels a distance d=22.1m in the positive x direction in a time t1=20.2s, at which point the jeep brakes, coming to rest in t2=7.38s. 1. What was the jeep's instantaneous velocity in the horizontal direction, in meters per second, when it began braking?  2. Using the result from question 1, what was the jeep's horizontal component of acceleration, in meters per squared second, during the braking period?
