PRE-LAB 3: Acceleration and Force 1. (3pts) In Part 1, you will repeat your Lab 2 Speeding Up experiment with a focus on forces. . Draw a free-body diagram of the forces acting a. on the cart. otes Draw a free-body diagram of the forces acting on the mass. b. Which forces in the two diagrams are equal? c. oipol 3. (4 pts) We will be using the same cart and motion sensor setup we used in last lab: Force...
HILL COLLISION III My Notes You push a box of mass 24.3 kg with your car up to an icy hill slope of irregular shape to a height 5.5 m. The box has a speed 11 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before elastically colliding with a smaller box of mass 12 kg. The boxes then fall off a...
please explain the answers. 8) I was a scout when I was a young boy. Each year the scouts would participate in the pine wood derby (look up pine wood derby if don't know what that is). In the pine would derby you build a toy car out of a block of pine wood. Each scout then races their car in a competition, by letting their car go down a ramp. The rules of the pine wood derby dictate that...

Suppose that the the time according to the equationxbP, where a is in me total distance moved by your car during these two phases is 56.7 m lers and rin secondh What are the units of (a) constant e and (b) con- when its...
Question 1 1 pts What is the kinetic energy of a man who weighs 980N who is riding in a car traveling 40 km per hour? Express your answer in Joules, but don't type the unit in the answer box. Round to the nearest whole number. (Careful with the units) 1 pts Astudent slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed. If the coefficient of kinetic friction between the...
