A football player launches a ball of mass m from the origin (0,0) with an initial speed v, with at an angle a above the horizontal. The ball lands on the ground at (d,0). Neglecting the drag, a) find out the expression of v, in terms of a and d. b) if d=45m, and a=45°, find out the total time of flight. c) Now consider drag force, F=-bv with b-constant, find a formula of the horizontal distance travelled by the ball x₁ with respect to origin when the ball reaches the maximum height yn. Express the answer as a function of a,g,vo,b and m. (F and v are drage force and velocity vectors respectively)

Back on Earth, a ball is thrown off a roof top with a horizontal velocity 8 m/s and a downward vertical velocity 5 m/s. It hits the ground 2.2 s later. What is the direction at which the ball hits the ground? Give the angle the velocity vector makes with vertical (straight down = 0° and horizontal = 90°). Use g = 9.8 m/s² if needed and neglect air friction. %3D Read carefully -- there are versions of this question with upward vertical velocity and another with downward vertical velocity.
A projectile is fired up an inclined plane (incline angle α) with an initial speed v0 at an angle β with respect to the horizontal (β > α) Let d denote the distance the projectile travels up the incline.a) Express d in terms of α, β, v0 and g.b) For what value of β is d maximal, and what is the maximum value of d?
For this problem think about a long jumper who takes off and lands from different heights. This is due to the Center of Gravity being higher when they leave the ground then when they contact the sand. If the jumper has a horizontal distance traveled of 7.5 meters and an initial horizontal velocity 6.1 m/s and a takeoff angle of 30 degrees. How far did the jumper fall vertically from takeoff to landing?
You're in an airplane that flies horizontally with the speed of 900 km/h (250m/s) when an engine falls off. Neglecting air resistance assume it takes 34 seconds for the engine to hit the ground. If the airplane somehow continues to fly as if nothing has happened what is the distance between the engine and the airplane at the moment the engine hits the ground?

You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0
An item with beginning speed v0 is projected from the edge of the roof of a structure of height H. The object's initial velocity produces an angle a0 with the horizontal. Don't think about air resistance. What is the speed of the item shortly before it hits the ground if a0 = -90 and the object is thrown straight down?
In my homework, I am asked to derive an equation for V0. The homework question is as follows: A howitzer fires a shell with a velocity of v0 at an angle Θ above the horizontal. The howitzer is on a plateau and the shell lands down in the plain below, a vertical distance d below the plateau and a horizontal distance L from where the howitzer is. Derive an expression for the magnitude of the initial velocity, V0, as a function of d, L, g, and Θ. Any help would be appreciated as I have worked on this problem for quite a while and I am not making progress.
