(6 )Suppose you're standing on the ground and throw a frisbee. You want the expression for the acceleration of a point on the edge of a frisbee (flying, rotating disk) in flight relative to yourself. If you know the acceleration of the frisbee's center of mass relative to yourself and the position of your point of interest on the frisbee's edge relative to the frisbee's mass center at a particular instant, what other information would you need?
nothing - you have all the information you need
the frisbee's angular acceleration
the frisbee's angular velocity
the frisbee's angular velocity and angular acceleration

2.A 31 kg skip attached to a steel rope on a crane is used to hoist bricks from the ground to the top of a construction site. The steel rope is wound onto a lifting drum with a diameter of 700 mm and rotational frequency of 52 revolutions per minute. The lifting drum is situated on the top floor which is 196 m high. How many seconds will it take to lift bricks, three quarters up the height of the building?

Dynamics problem
The acceleration of a point moving on a vertical line is given by the equation a = 12t – 20. It is known that its displacement s = -10 m at time t = 0 and that its displacement s = 10m at time t = 5 seconds. Derive the equations for itsa.) velocity andb.) displacement

You walk along the beach towards a dock while your friend rows a boat towards the same dock on a flat lake. Your friend's boat approaches the dock on a straight course, but also rotates about its center-of-mass since your friend is not pulling evenly on the oars. If you knew your own velocity (vwalker), the magnitude of boat's angular velocity (thetaboat), and radius vector from yourself to your friend in the boat (rfriend) at any given time, you could use the following equation to calculate the your friend's velocity:
vfriend = vwalker + (thetaboat)k x rfriend where k is a unit vector in the vertical direction.
True
False

You and a friend are raising a beam, but your friend's rope is too short so you lift him off the ground. At the current time, everything is static. The tension in your cord is 1045.6 N, the mass of the beam is 15 kg, and the mass of your friend is 85 kg. The length of the beam is 4.9 m, d = 3.9 m, theta = 43.5 degrees, phi = 62.5 degrees. If you choose the base of the beam as the origin, and the positive torque direction as counter-clockwise, what is the torque from your cord on the friend+beam system?

A 150mm long link swings on a pivot from its vertical position of rest to the right through an angle of 60 degrees and returns to its initial position at uniform velocity. During that period, a point P moving at uniform speed along the center line of the link from a point at a distance of 30mm from 0, reaches the end of the link. Draw the locus of the point P
