A human (88 kg) goes skydiving from space and goes into a vertical dive trying to break their speed record. How fast are they traveling if they fall for a full mile while in "space" aka no air resistance?
Homework Answers
Given :
m = 88 kg
initial speed (u) = 0 m/s
distance traveled (d) = 1 mile = 1609.34 m
Using formula : v2 - u2 = 2ad
Here, a = g = 9.81 m/s2
v2 - u2 = 2gd
v2 - (0)2 = (2)(9.81 m/s2)(1609.34
m)
v2 = 31575.2508 m2/s2
v
= 177.69 m/s

A 6000-kg cart carrying a vertical rocket launcher moves to the right at a constant speed of 30.0 m/s along a horizontal track. It launches a 40.3-kg rocket vertically upward with an initial speed of 46.1 m/s relative to the cart. How high will the rocket go? Where, relative to the cart, will the rocket land? How far does the cart move while the rocket is in the air? At what angle, relative to the horizontal, is the rocket traveling...

1. A marble is fired into the air at 12m/s at an angle of 35° from vertical. It lands 1.25 m lower than its launch height. What is the maximum height that it reaches above its landing location? When does it reach this height? When does it land? What is its velocity (speed and direction) when it lands? Max height Time at max height = Time of landing- Velocity at landing - 2.

Two asteroids are far from any gravitation and are initially at rest in space. The mass of asteroid one is 5.7 x 1018 kg and the mass of asteroid two is 3.6 x 10 17 kg. After they fall towards eachother the first asteroid has a speed of 31 m/s right before impact. How fast is the second asteroid moving right before impact?
