A bowling ball weighing 71.2 is attached to the ceiling by a 4.00rope. The ball is pulled to one side and released; it then swingsback and forth like a pendulum. As the rope swings through itslowest point, the speed of the bowling ball is measured at 4.20.


At that instant, find the magnitude of the acceleration of thebowling ball.

Question Two

A rocket is fired at an angle from the top of a tower of height ho = 50.0 m. Because of the design of the engines, its position coordinates are of the form

x(t) = A + Bt2 and y(t) = C + Dt3

where A, B, C, and D, are constants.

Furthermore, the acceleration of the rocket 1.00 s after firing is a = (4.00i + 3.00j) m/s .

Take the origin of coordinates to be at the base of the tower.

(a) Find the constants A, B, C, and D, including their SI units.

(b) At the instant after the rocket is fired, what are its acceleration vector and its velocity?

(c) What are the x- and y-components of the rocket's velocity 10.0 s after it is fired, and how fast is it moving?

(d) What is the position vector of the rocket 10.0 s after it is fired?

Figure 2

A bowling ball weighing 71.2 N is attached to the ceiling by a 3.80-m rope. The ball is pulled to one side and released; it then swings back and forth as a pendulum. As the rope swings through the vertical, the speed of the bowling ball is 4.20 m/s.

(a) What is the acceleration of the bowling ball, in magnitude and direction, at this instant?

(b) What is the tension in the rope at this instant? (10 marks)

1) A tetrahedral is attached to a swivel in the ceiling by a light cord of length L. When the ball is hit by a paddle, it swings in a horizontal circle with constant speed v, and the cord makes a constant angle Ī² with the vertical direction. The ball goes through one revolution in time T. Assuming that T, the mass m, and the length L, of the rope are known, derive algebraic expressions for the tension F2 in the cord and the angle Ī².

14.52 - A small sphere with mass m is attached to a massless rod of length L that is pivoted at the top, forming a simple pen- dulum. The pendulum is pulled to one side so that the rod is at an angle 8 from the vertical, and released from rest. (a) In a diagram, show the pendulum just after it is released. Draw vectors repre- senting the forces acting on the small sphere and the acceleration of the sphere. Accuracy counts! At this point, what is the linear acceleration of the sphere? (b) Repeat part (a) for the instant when the pendulum rod is at an angle /2 from the vertical. (c) Repeat part (a) for the instant when the pendulum rod is vertical. At this point, what is the linear speed of the sphere?
