In the figure, the upper ball is released from rest, collides with the stationary lower ball, and sticks to it. The strings are both 55.0 cm long. The upper ball has a mass of 1.60 kg and it is initially 10.0 cm higher than the lower ball, which has a mass of 3.50 kg.
A. Find the magnitude of the momentum of the 1.60-kg ball just before it collides with the 3.50-kg ball.
B. Find the speed of the two balls (now stuck together) at the instant immediately after the collision.
C. Find the frequency of the pendulum motion after the collision.
D. Find the maximum angular displacement of the motion after the collision
A figure skater begins spinning counterclockwise at an angularspeed of 4.7 π rad/s. during a 4.9 s interval, she slowly pulsher arms inward and finally spins at 8.2 π rad/s. what is heraverage angular acceleration during this time interval?
Two cylindrical glass beads each of mass m = 32 mg are set on their flat ends on a horizontal insulating surface separated by a distance d = 3 cm. The coefficient of static friction between the beads and the surface is μs = 0.3.
Choose one between these two: This assignment will be sent through 'safe assign' so no plagiarism please. Present both sides on "abortion vs. the right to life," and b) take a stand on the issue. What are the determinants of population health, and b)..
An automobile of mass 1500 kilogram moving at 25.0 m/s collides with a truck of mass 4500 kilogram at rest. Determine the final velocity of that car and truck just after the collision
A 40 kg child standing on a frozen pond throws a 0.5 kg stoneto the east with a speed of 5 m/s. Negelcting friction between thechild and the ice, what is the recoil velocity of the child
A superconductor in a magnetic field obeys the relationship B(T) = B(0) [1 – (T/Tc)2]. If the superconductor has a Tc of 20K and it is operated at T = 4.2K the critical field is 30T. Determine the maximum operating temperature if the material is used..
He is unable to get to the other sidebecause of a lack of friction between hisshoes and the ice. To overcome thisdifficulty, he throws his 1.2 kg physics textbookhorizontally toward the north shore, at a speed of6.7m/s. The acceleration of gravity..
