2. Please include units in your answer.
- Use the correct unit abbreviation.
- Include a space between the value and the unit.
- To express exponents in your units, use a ^. For example, m/s2 would be m/s^2.
What is the magnitude of the acceleration of a modified Atwood machine if the mass of the cart is 8 kg and the hanging mass is 17 kg? (Use g = 9.8 m/s2. Express your answer to one decimal point.)
3.
In a completely frictionless Newton's Cradle toy, the change in speed of the balls coming in and those going out is zero. This is because the net force at the time of the collisions is equal to the weight of the number of balls interacting.
