STARWARD ACADEMY WORKSHEET # 2 MOMENTUM DUE: 1. Calculate the momentum of an object if: (a) its mass is 4.0 kg and its velocity is 8.0 ms-1 (b) its mass is 500 kg and its velocity is 3.0 kms-1 (c) a force of 20 N is applied to it for 6.0 s and it moves from rest (d) its mass is 2.0 kg and it falls from rest for 10 s (assuming g = 10 ms-1 or 10 Nkg-1). 2. A car of 1200 kg is pushed along a level road by two men. If they use a force of 800 N and frictional forces acting against

Carmela Marie C. Beloso Why Do I Want to Become an Engineer? Why do I want to become an engineer? Is a question I often ask myself and often have difficulty answering. When other people are asked with this question‚ they would have instant answers such as: It’s been my dream since I was little‚ I like machines‚ It’s because of LEGO.‚ My father is an engineer.‚ and etcetera. I wish I could have the same answer as them. I wish I could tell a story where when I was young‚ I would take my toys apart

Pendulum Problems ACTIVITY 1: Copy and paste the example problem and the steps‚ so that the steps are in the correct order into a new Word document and upload it to Moodle. Example Problem 1: A hypnotist swings her watch from 20.0cm chain in front of a subject’s eyes. What is the period of the swing of the watch. Thus‚ we see that the pendulum used by the hypnotist has a period of 0.898s. | Before we can use this formula‚ however‚ we must ensure all our variables are in the correct units.

TUTORIAL 1 1. Convert the following temperatures to their values on the Fahrenheit and Kelvin scales: (a) the boiling point of liquid hydrogen‚ –252.87°C (b) the temperature of a room at 20°C. 2. A constant-volume gas thermometer is calibrated in dry ice (–80.0°C) and in boiling ethyl alcohol (78.0°C). The respective pressures are 0.900 atm and 1.635 atm. (a) What value of absolute zero does the calibration yield? (b) What pressures would be found at the freezing and boiling points of water
