Please grab a whiteboard and pens and answer the following questions…

​

If m₂ is 5.0 kg, what must the mass of m₁ be so the system exists at equilibrium?

F_g1ll = F_g2ll

Ans: 7.9 kg

A rollercoaster ride is shown in the diagram below.  The mass of the car and Ms. Spearman is 700.0 kg and the coefficient of friction is 0.0500. 

Ms. Spearman wanted me to mention that majority of the mass was the car.

(a) Determine the force that must be applied to the car as it is pulled

up the hill at a constant speed of 1.00 m/s. 

(b) The car is released at point A with speed 1.00 m/s. Find the speed

at point B.

Inclines Lab

1. Finding Coefficient Friction of an incline!
2. Please form a group of 2 to complete the following lab:
3. Hand in one completed lab report, including a graph, per pair
4. If you want take 2 sheets and make a rough copy!
5. Due at the start of next class
