Calculate the horizontal distance that the object will travel. HELPPP ASAPPPP!!!!!
Explain how the mass of your race car will affect its performance with reference to Newton’s 2nd law of motion. Use the terms force, mass, and acceleration.
A box of mass m slides up a ramp with initial velocity +v0. The kinetic friction force on the box has magnitude f. Which of the following is a correct equation that could be used to determine the acceleration a of the box?
A ball is equipped with a speedometer and launched straight upward. The speedometer reading three seconds after launch is shown at the right. At what approximate times would the ball be moving upward and display the following speedometer readings?
A car moves with a constant speed of 216 km/h. Express this speed in meters/seconds and calculate the distance traveled in 30 seconds in meters.
Explain the advantages and disadvantages of having a racecar with a small mass in reference to Newton’s 1st law of motion. Use the term inertia in your answer.
Part 1. In chapter 5, the mnemonic SAMPLE is used to gather information about an injured person. For this assignment, explain how to use SAMPLE to gather information about an injured person. What does each letter stand for and what exact questions will you ask the injured person to gain this information? Part 2. In the book, it is explained in detail how to put a person into recovery position, read that information and then...IN YOUR OWN WORDS, explain to me how to put a person into recovery position. I know that you will want to copy and paste the words but that is not what I want! I want you to type it up the way you would explain it to someone if you were telling someone how to put another person into recovery position. We are going to work on this in class and should assist you with this!
Is the weight lifter doing the same amount of work when he lifts the 1200N barbell 1m the same as when he lifts the same barbell 2m? Explain answer Is my answer correct in the first problem?

(a) How much work is done when you push a crate horizontally with 150 N across a 20 m school floor? (b) If the force of friction on the crate is a steady 50 N, what will be the KE gained by the crate? (c) How many joules of energy will be turned into heat?
Two hockey pucks with mass 0.1 kg slide across the ice and collide. Before the collision, puck 1 is going 8 m/s to the east and puck 2 is going 7 m/s to the west. After the collision, puck 1 is going 7 m/s to the west. What is the velocity of puck 2?
