There are 360° in a circle. The length of the circle is the circumference, 2πr. Therefore, s = (1/12)(circumference).Motion Q. A ball rolling west at 3.0 m/sec has a mass of 1.0 kg. It collides with a second ball whose mass is 2.0 kg and is stationary. After the collision, the first ball moves, south. Determine the momentum and speed of each ball after the collision. A. We assume that the collision is elastic.

Jan 31, 2016 · #m# - the mass of the ball #v# - its velocity #r# - the radius of the circle described by the ball's motion. The centripetal force here will be the sum of the two horizontal components of #T_1# and #T_2#. Looking at the diagram, the radius #r# can be written as . #r = L * sin(60^@)# The weight of the ball will be equal to . #G = m * g# In time t b - t s the balloon has dropped a distance d = ½g (t b - t s) 2 = 9.6 m and is therefore a distance 40 cm above the man. Problem: A boy wants to throw a can straight up and then hits it with a second can. He wants the collision to occur 4 m above the throwing point. In addition, he knows that the time he needs between throws is 3.0 ...

Nov 20, 2010 · A. Speed and Acceleration 1. A 2.0 kg mass swinging at the end of a 0.50 m string is traveling 3.0 m/s. What is the a. centripetal acceleration of the mass? b. centripetal force on the mass? 2. A person standing at the Earth's equator has what rotational speed? (R = 6.38 x 106 m) 3. A building is located 28º north of Earth's Equator. A bob of mass m is suspended from a fixed point with a massless string of length L (i.e., it is a pendulum). You are to investigate the motion in which the string moves in a cone with half-angle θ. In other words, the bob is moving around in a horizontal circle with constant speed. a) [4 points] Draw a free-body diagram of the bob.
Teeth: The jagged faces projecting outward from the circumference of the gear, used to transmit rotation to other gears. The number of teeth on a gear must be an integer. Gears will only transmit rotation if their teeth mesh and have the same profile. Pitch Circle: The circle that defines the "size" of the gear. The pitch circles of two meshing ... 6.3 A ball of mass 0.5 kg is released from rest at point A, which is 5 m above the bottom of a tank of oil, as shown in the figure. At B, which is 2 m above the bottom of the tank, the ball has a speed of 6 m/s. The work done on the ball by the force of fluid friction is a) +15 J. c) –15 J. b) +9 J. d) –9 J. A B Water temperature T ( C)
Archimedes discovered formulae for the volume and surface area of a sphere, and may even have been first to notice and prove the simple relationship between a circle's circumference and area. For these reasons, π is often called Archimedes' constant. His approximation 223/71 π 22/7 was the best of his day. (Apollonius soon surpassed it, but ...
