1. A ball is shot at a ground level at an angle of 60 degrees with the horizontal with an initial velocity of 100 m/s, determine the following: a. Velocity of the ball after 2 sec. b. The time it takes for the ball to hit ground. c. The horizontal distance from the initial position to the point where the projectile strikes the ground.

7. A bullet is fired downward at an angle of 30° below the horizontal. 3.20 seconds later, the bullet hits a target that is 120 m horizontally to the right of the starting point. Let x direction be to the right and y direction point upward. a) Find vox, the x-component of the initial velocity of the bullet. b) Find the y-component of the initial velocity of the bullet. Voy,

A firework is launched with an initial velocity of 30 m/s at an angle of 65 degrees with respect to the horizontal.   The horizontal component of the firework’s velocity, just before it reaches the peak of its motion (where it will explode). b. The vertical component of the firework’s velocity, at a time 0.5 seconds after it was launched. c. The magnitude and direction of the acceleration of the rocket, at a time 0.5 seconds after it was launched.

24. A shell is fired with a horizontal velocity in the positive x direction at a speed of 330 m/s from the top of an 80- m high cliff. The shell strikes the ground 1330 m from the base of the cliff. What is the magnitude of the velocity of the shell as it hits the ground? Hint: you need to determine horizontal and vertical components of the final velocity first, from the kinematic equations, then calculate magnitude of the velocity. While the horizontal velocity remains constant, the vertical velocity does not. You will need time of flight to determine the latter. 80 m 1330 m A) 4.0 m/s B) 9.8 m/s B) 9.8 m/s C) 82 m/s D) 170 m/s (E) 332 m/s

Steph Curry launches a basketball from a height of 2.36 m above the ground from the free throw line, which is 4.191 m to the left of the center of the hoop. The basketball makes it through the hoop, which is 3.048 meters above the ground, 1.13 seconds later. a.) what is the basketball's velocity when it leaves Steph's hands? b.) what is the basketball's velocity as it passes through the hoop?

2. A group of students conducted a projectile experiment in which they fired a projectile at an unknown angle with varying speed. Students took the following data for projectile range and speed. Determine: a. What kind of graph comes out if initial velocity vs. range is plotted? R(m) Volm/s) 0.2 1.71 0.4 2.42 0.6 2.97 0.8 3.43 3.83 1.2 4.2 1.4 4.53 1.6 4.84 1.8 5.14 2 5.42 b. What is the linearization method for this graph? c. Make the linearized graph and determine its slope with its units. d. Determine the initial angle at which the projectile was launched.

5. A projectile is launched at an angle of 50° with the horizontal and a speed of 25 m/s. a) What is the Range of the projectile? b) What is its height after 1.5 second?

Question 3

You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball.
