In the projectile motion experiment, a steel ball is rolled down a track starting from a height h above end of the track. The ball flies off of the end of the track and then strikes the floor at some horizontal distance d out from the projection of the end of the track down onto the floor. The apparatus is moved to a different table where the end of the track is now 50% greater than h. How does the new horizontal distance compare to the previous? O The new distance is 1.2 d. O The new distance is 0.7 d. The new distance is 1.7 d. The new distance is 1.6 d. O The new distance is 2.0 d. O The new distance is 1.5 d. O The new distance is 1.4 d.

You will be studying the two-dimensional motion of a projectile moving in a vertical plane. We assume that there is no air resistance on the projectile. This lab is based on the theory presented in Chapter 4 of the Knight (5th edition) textbook. The diagram below shows the trajectory of a ball projected from the origin at time t=0. On the axes below the diagram, sketch the respective graphs for the projectile motion. S t=0 t S How can the acceleration components ax and ay be obtained from the vxt and vyt graphs?
The banded archerfish is a species of fish that lives in mangrove estuaries in Asia and Oceania. It has a unique and highly effective hunting strategy: it shoots an incredibly precise stream of water out of its mouth at almost ten meters per second, knocking insects and other small animals into the water from nearby branches! Pom Fbug (t) Ө = Our hero, a hungry archerfish, has spotted a big, delicious bug sitting on a branch a height ħ above the surface of the water. The archerfish can shoot its water jet at a speed of vo. The archerfish wants to knock the bug sideways off of the branch, so it decides to shoot so that its water jet is moving horizontally at the moment when it strikes the bug. The final goal of this problem is to find the horizontal distance, d, from the branch, and the angle above horizontal, 0, at which archerfish should shoot. d (a) What are the position and velocity of the water droplet as a function of time and the position and velocity of the bug as a function of…
Please help with parts g and h Two velocity vectors are defined as follows: v1 = 40.0 m/s, 50.0 degrees cw from the +x axis v2 = 30.0 m/s, 75.0degrees cw from the -y axis d) Calculate the x- and y-components of v2. Write the vector v2 in terms of its components using unit vector notation. e) Calculate the x- and y-components of the change in velocity defined as Δv= v2-v1. Write the vector Δv in terms of its components using unit vector notation. f) Sketch the vector Δv on an x-y grid. Define a relevant angle symbolically whose numerical value you will calculate in the next part. g) Calculate the magnitude and direction of the vector Δv. h) Finally, write the vector Δv in terms of its magnitude and direction.
An airplane releases a ball as it flies parallel to the ground at a height of h as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height h from the release point, find the speed v of the plane in terms of h and g. Neglect any effects due to air resistance. Note that this type of question is to be solved symbolically, ie, using only the symbols h and g, instead of plugging in numbers.
We want to find the coefficient of restitution e between the ball and the floor. We will be able to measure the time of flight between subsequent bounces, but not the velocities before and after each impact. Question 1 a. Using the kinematics equation for position, find a relationship between the time of flight tn and the velocity of the ball after the nth bounce. You should obtain a quadratic equation that has two solutions for the time tm, but only one of them represents the time of flight. b. Using the kinematics equation for velocity and the relationship determined in the previous step, find the relationship between the velocity right after the nth bounce and the velocity right before the (n +1)th bounce? c. Given your answers to the previous parts of this question and the definition of €, find the coefficient of restitution e in terms of the subsequent times of flight tn and tr+1.
A person shoots a loaded gun at a target that is 65 m away. The center of the target is at the same height as the gun. The person aims the hun upwards at an angle so that the bullet hits the center of the target. The bullet leaves the gun at a velocity of 210 m/s. a. What is the angle of the gun in degrees from the positive x axis?

A ball is kicked from the ground at an angle of Q = 51 degrees with respect to the horizontal. The ball is in the air for a time tm = 1.1 s before it lands back on the ground. a. Numerically what is the total horizontal distance dm in meters, travelled by the ball in the time tm?
A skier is at the top of a hill with height h. Starting from rest, the skier goes down to a flat area. On this flat area, there is a section of the slope with length D where the snow has melted (there is friction here). After passing the melted section, the skier goes up a smaller hill of height h2. At the top of this hill there is a drop off and the skier launches off of it with a horizontal speed. At what horizontal distance from the base of the jump does the skier land?
You are assigned to do some calculations for a movie stunt that involves a car on a straight road. The road, pictured above, has a hill that rises 8.0 m above the flat region. The top of the hill is a circular arc of radius 20 m. You need to determine whether a car traveling under certain conditions will lose contact with the road at the top of the hill. There is a stop sign 50 m from the beginning of the hill. You are to assume that a car of mass 1600 kg accelerates uniformly from rest at the stop sign, has a speed of when it reaches the beginning of the hill, and then coasts with the engine off. Assume energy losses due to friction and air resistance are negligible. Calculate the magnitude of the acceleration of the car during the first 50 m. Calculate the time it takes the car to reach the beginning of the hill. Calculate the magnitude of the net force required to accelerate the car during the first 50 m.
