A wad of clay of mass m1 = 0.51 kg with an initial horizontal velocity v1 = 1.97 m/s hits and adheres to the massless rigid bar which supports the body of mass m2 = 1.37 kg, which can be assumed to be a particle. The pendulum assembly is freely pivoted at O and is initially stationary. The distance L = 1.01 m. Determine the angular velocity ω of the combined body just after impact. Why is linear momentum of the system not conserved?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
