PHSX 211 1nd Edition Lecture 11 Outline of Last Lecture Practice ProblemsI. Draw a Free body diagram for the following situation:a. A block of mass m is sliding downward on a slope. b. What is the acceleration equation with respect to the variables?II. For the diagram you drew above, what would be the time it would take for the 10 kg block to slide down the 8 m slope that is 20 degrees to the horizontal, with an initial velocity of 1.2 m/s, and a coefficient of kinetic friction of .2?III. If you had 5 spheres in the air:a. Sphere 1: i. 50 gii. V0 = 0b. Sphere 2:i. 100 gii. V0 = 0c. Sphere 3:i. 50 gii. V0 = 20 m/s downd. Sphere 4:i. 100 gii. V0 = 20 m/s downe. Sphere 5:i. 50 gii. V0 = 20 m/s upIV. What would their order be of equal or increasing acceleration?Outline of Current Lecture Practice ProblemsI. What will happen when a magnet is attached snuggly and hanging in front of an iron cart?II. Consider the forces in the follow situation:a. A women pulling a sledb. A ball falling towards the earthIII.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Current LecturePractice ProblemsIV. What will happen when a magnet is attached snuggly and hanging in front of an iron cart?a. The magnet nor the iron cart will not move because neither has a way of initiating their acceleration towards each other or they do not have a way of propulsion.V. Consider the forces in the follow situation:a. A women (w) pulling a sled (s) rightF (w on Gravity)WOMENF (w on Ground) (Propulsion) F (Ground on w) (Propulsion)F (s on w)F (w on s)SLEDF (s on Ground)F (Ground on s) (kinetic friction)F (Gravity on w)b. A ball falling towards the earthi. The ball and the earth have forces equal in magnitude acting against eachother. The force of the ball on the earth is equal but opposite to the force of the earth on the ball. However, the mass of the ball is relatively small to the mass of the earth, so it’s acceleration has to be quite a bit larger than the earth’s acceleration in order for their forces to be equal in
