Here, mA = 1.85 kg and
mB = 8.40 kg. The string connecting the two
objects is of negligible mass and the pulley is frictionless. The
objects start from rest and move with constant
acceleration.
A pulley and string arrangement is used to connect two objects A and B as shown in the diagram below Here, mA -1.85 kg and m acceleration. 8.40 kg. The string connecting the two objects is of negligible mass and the pulley is frictionless. The...

10 pts Question 6 6) A mass of 8 kg is moving at 20 m/s in the +x direction and collides in a perfect elastic collision with a 3 kg mass moving in the +x direction at 6 m/s. If the masses are in contact for 0.15 seconds, what is the average force on the 8 kg mass in Newtons? Include a negative sign if in the negative x direction.

a) An oil droplet with a mass of 7.20 x 10-16 kg is moving upward at a constant speed of 2.0 m/s between two horizontal charged plates. If the electric field strength between the plates is 2.20 x 104 V/m what is the charge on the oil droplet? Express your answer in the format of a.bc x 10-de C b) In a Millikan-type experiment, two horizontal charged plates are 2.5 cm apart. A latex sphere of 1.3 x 10-15 kg...

10 pts Question 8 Am 1= 24.0-kg object and a m 2 = 6.0-kg object are suspended, joined by a cord that passes over a pulley with a radius of R= 10.0 cm and a mass of M = 3.60 kg as seen in the Figure. The cord has a negligible mass and does not slip on the pulley. The pulley rotates on its axis without friction. The objects start from rest d = 4.20m apart. Treat the pulley as...

6. (10 pts) A patient with a broken leg was placed in traction using the system shown below at left. Once the cast is off of the foot, the system can be modeled as shown at right where m is the mass of the cast. In a most unfortunate incident, the cast slips off of the patient's foot and is flung by the traction system. In this problem, model...
