Bubba is working on the loft in the barn his farm one day. The loft is 3.54 meters tall. Bubba decides to throw a hammer downward with an initial downward velocity of 3.38 m/s in order to hit a mouse that he sees crawling across the floor of the barn. a) How long does it take for the hammer to reach the ground? b) How fast is the hammer moving when it hits the ground?

A sky diver drops his smuggled 1kg weight from physics lab out of the air plane before he jumps, which is flying horizontally going 175 m/s at a height of 2 km. IF WE ASSUME NO AIR RESISTANCE, what is the Velocity (magnitude and direction) when it hits the ground? If an object initially at rest is given a velocity of: V-1.93 m/s and vy 2.51 m/s. What is the magnitude and direction its displacement after a time of 3.50...

Onur drops a basketball from a height of 10 m on Mars, where the acceleration due to gravity has a magnitude of 3.7 . We want to know how many seconds the basketball is in the air before it hits the ground. We can ignore air resistance. Which kinematic formula would be most useful to solve for the target unknown? Choose 1 answer: 2

While unrealistic, we will examine the forces on a leg when one falls from a height by approximating the leg as a uniform cylinder of bone with a diameter of 2.3 cm and ignoring any shear forces. Human bone can be compressed with approximately 1.7 × 108 N/m2 before breaking. A man with a mass of 70 kg falls from a height of 7 m. Assume his acceleration once he hits the ground is constant. For these calculations, g =...

1. The Earth is moving around the Sun along an orbit that is approximately circular. The radius of the orbit is 150 million kilometers. The Earth can complete a full circle in approximately 365.25 days (that is, one year). Within half a year, what is (a) the average velocity and (b) the average speed of the Earth relative to the Sun? Express your answers in kilometers per second, km/s. (Hint: draw a diagram of the orbit.) 2. Spider-Man jumped off...

Assume a rocket is launched from a platform that is 20 meters high at angle of 53 degrees. While the rocket still has gasoline, it uniformly accelerates, maintains a launch angle relative to the ground, for four seconds and reaches a velocity of one hundred meters per second starting from rest. You may neglect any air resistance. Part 1: What is the max height the rocket can have before it falls back to ground? Part 2: How much time does...
