You create a diffrent kind of pendulum by swinging a meter stick (mass m) on its end. It swings with small oscillations. Draw a free body diagram and try to determine the relationship between the angular acceleration and the angle just like you did with the simple pendulm. Determine the angular frequency w ( I=1/3 ML ^2)
A 150g ball and a 250g ball are connected by a 34cm long, massless, rigid rod. The balls rotate about their center of mass at 130 . what is the speed of ball of 150 g.
Assume the Earth is in uniform cicular motion about the sun. Explain how to determine the angular velocity of the Earth
A 24N crate is held at rest on a frictioneless incline by a rope that is parallel to the incline. The incline is 25 degrees above the horizontal
A block of mass 0.570 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m.
An proton (m = 1.67 ´ 10-27 kg and q = 1.6 ´ 10-19 C) travelling at 2.7 × 105 ms-1 enters a magnetic field of 1.2 T at right angles to the direction of motion of the electron. What is the centripetal force on proton.
2 crewmen pull a raft, 1 crewman pulls with a force of 130 newtons at 34 degreees relative to the forward position on the raft. the 2nd crewman on the opposite side pulls at 45 degrees. Illustrate what force should the 2nd crewman pull so that the..
Two particles of masses m and 3.00m are moving toward each other along the x-axis with the same speed v. They undergo a head on elastic collision and rebound along the x- axis. Find out the final speed of the heavier object.
a block of mass m=0.2kg , in simple harmonic motion, has an amplitude of 3.5cm and a maximum speed of 70 cm/s. What is the angular frequency for the oscillation in rad/s?
A major-league catcher gloves a 92 {rm mi}/{rm h} pitch and brings it to rest in 0.15 {rm m}.If the force exerted by the catcher is 803 {rm N}, what is the mass of ball.
What is the value of the composite constant (Gmer2e), to be multiplied by the mass of the object mo in the equation above
Assume that the sun runs out of nuclear fuel & suddently collapses to form a white dwarf star, with a diameter equal to that of the Earth. Estimate the new rotation period of the Sun.
A loudspeaker of mass 19.0 is suspended a distance of = 2.00 below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of = 3.30. Illustrate what is the tension in each of the cables?
