A ball has an initial velocity of 160 m/s at an angle of 30 degrees horizontally. This means that the initial vertical velocity of 80m/s and its initial horizontal velocity is 139m/s. Find its position and velocity after 5 seconds. a. Horizontal Displacement b. Find the Vertical Displacement c. Horizontal and Vertical Component of Velocity

Cannon problem: There is a new cannon entering service. The artillery crews need some information about the cannon's behavior so they can make adjustments to the firing angle as needed. When the engineers tell the artillery crew the range to the target, the crew must be able to calculate and set the proper firing angle for the cannon quickly. a) In order to calculate the proper firing angle what do they need to know about the cannonball leaving the cannon? (Ignore the height of the cannon above the ground. For now we will assume it makes little difference) b) Given your answer for part a, we need to identify the point in the cannonball's flight when it has its "initial velocity". The cannonball is clearly moving inside the barrel of the cannon, but at which point in the cannonball's path do we mark the initial velocity? The cannonball is packed onto a mass of gunpowder in the base of the cannon. When the powder is ignited, the chemical reaction produces gas and a large amount of heat…

When there is air resistance present how to the velocity and acceleration vectors behave?   a.The acceleration and velocity vectors are both constant magnitude but continually change direction.   b.The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory   c.The acceleration vector is perpendicular to the trajectory and the velocity vector is at a tangent to it.   d.The acceleration changes throughout the flight with its x-component opposite the direction of motion. The velocity vector is at a tangent to the trajectory

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 cannonball is fired from a height of 25 m above ground level, with an initial speed of 22.36 m/s and at an angle of 63.4⁰ above the horizontal. The cannonball lands at ground level. a. How long was the ball in the air (the “hang time")? b. How far does the cannonball travel horizontally? c. What is the final speed of the cannonball just before making contact with the ground?

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.

A conveyor belt at a recycling plant launches bottles and bottle caps into the air, so that an automatic image recognition device can count them. They land at the same height at which they are launched. Glass bottles are launched at an angle of 35.0° above the horizontal, and land after 0.500s. a) Solve for the initial speed at which the bottles are launched. b) Solve for the horizontal displacement at which the bottles land. Plastic bottle caps are launched at an angle of 40.0° above the horizontal, with a speed of 4.85 m/s. The image recognition sensor captures their pictures at a height of 0.350 m, as they are moving upwards. c) Solve for the time that the imaging sensor captures a bottle cap image. d) Solve for the angle of the velocity vector (from the horizontal) when a bottle cap image is captured.

A soccer player kicks a ball with an initial velocity of 10 meters per second at an angle of 30 degrees above the horizontal. The magnitude of the horizontal component of the ball's velocity is Select one: O a. 10 m/s O b. 8.7 m/s O c. 5.0 m/s O d. 9.8 m/s

During a football game Aiden kicks a ball from the ground at the 30-yard line. He gives the ball an initial speed of 20 meters per second, at an initial angle of 36.9 degrees. a. One second after the kick how high is the ball above the ground measured in feet? b. How far away will the ball land on the ground measured in yards?
