1.A spring-loaded dart gun with a spring constant K= 2000 N/m is used to shoot a dart with a mass .20kg straight up into the air, and the dart reaches a maximum height of 10 meters. How far did the spring need to be compressed? 2. If i wanted to measure the amount of potential energy in the spring inside my nerf gun, with some nerf darts, what is an easy way i could do it? Explain the steps you...

A spring-gun projects a small rock from the ground with speed
v0 at an angle ?0 above the ground. You have been
asked to determine v0. From the way the spring-gun is
constructed, you know that to a good approximation v0 is
independent of the launch angle. You go to a level, open field,
select a launch angle, and measure the horizontal distance the rock
travels. You use g = 9.80 m/s2 and ignore the small height
of the end...

Problem 1. You aim a BB gun at a monkey hanging from a "tree." At the instant the BB is fired, the monkey drops from the tree. First, we estimate that the initial angle of the BB gun is 30° above horizontal and aimed directly at the monkey, and the tree the monkey falls from stands 5 m away. The BB has an initial speed of about 10 m/s, we'll neglect air resistance and use that he acceleration İom gravity...

At a height h = 44.0 m above the ground a rocket is fired at an initial speed v0 = 168.0 m/s at an angle θ = 27 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component...

You toss a ball from a balcony. When the ball leaves your hand, it is 10.0 meters above the ground and has a velocity of (10.0 m/s, 45.0 degrees above the horizontal). Ignore air resistance. (let's take the x-direction to be aligned with the horizontal motion and the y-axis to be upward.) A) How high above the ground does the ball go, and how much time does it take to reach max height? B) Determine the total time of flight....

Time in air Five balls are all at the same height near the surface of Earth. One is dropped from rest but the others are launched horizontally. Using the information given in the table below, state how long it will take for each ball to fall to the ground after being launched. Ignore air drag.

Newton’s Cannon Imagine you fired a cannonball such that the range of that ball was slightly longer than the radius of the Earth. As that ball fell back down, it would miss the ground and continue to fall. If we can ignore any air resistance or collisions with other objects, then we can say the ball would continue to fall forever, just missing the ground, and thus be in orbit. Assume all orbits here are perfectly circular and pretend that...

Procedure: Fire a practice shot. Locate the landing point on the floor then secure a piece of white paper to the floor (centered about the landing point). Cover the sheet with a piece of carbon paper and tape it down. 1. Shoot the ball at least 5 times. Take care not to disturb the position of the launcher during the shots. 2. Measure the vertical height H of the projectile launcher from the floor. (Use a plumb bob determine the...
