| Physics questions (ten points to first correct)?
What is the length of a pendulum that has a period of 2.3 seconds? A 30 kg box is pulled across a floor with 40 N of force. what is the coefficient of friction between the box and the floor? If the same box in the above question is put on a ramp adjusted to an incline of 34 degrees so that when tapped, it slides at a constant speed, what is the coefficent of friction with the ramp? |
