Explain why each drug could be fatal to a cell. • Vicritine (Oncovin): damages the mitotic spindle • Doxorubicin (Adriamycin): binds to DNA and blocks mRNA synthesis.

A sanding disk with rotational inertia 1.8 10-3 kg·m2 is attached to an electric drill whose motor delivers a torque of 12 N·m about the central axis of the disk. What are the following values about the central axis at the instant the torque has been applied for 195 ms? (a) the angular momentum of the disk

A 30.0 mu F capacitor initially charged to 30.0 mu C is discharged through a 2.10 kOmega resistor. How long does it take to reduce the capacitor’s charge to 6.00 mu C?

A 0.25 kg skeet (clay target) is fired at an angle of 28 degrees to the horizon with a speed of 25 m/s. When it reaches the maximum height, h, it is hit from below by a 15m g pellet traveling vertically upward at a speed of 230 m/s. The pellet is embedded in the skeet. How much higher, h’, did the skeet go up?

An object at rest on a flat, horizontal surface explodes into two fragments. One fragment is 7 times as massive as the other. The heavier fragment slides 8.70 m before stopping. How far does the lighter fragment slide? Assume that both fragments have the same coefficient of kinetic friction.

A loudspeaker of mass 25.0 {rm kg} is suspended a distance of h = 1.60 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.50 {rm m}.

A 65.0 kg person throws a 0.0450 kg snowball forward with a grounf speed of 30.0 m/s. A second person, with a mass of 60.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.50 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard friction between the skate and the ice.

A 3.40 kg steel ball strikes a wall with a speed of 7.0 m/s at an angle of 60.0° with the surface. It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball?

A 1210-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam. Using the data shown in the figure, find (a) the magnitude of the tension in the wire and the magnitudes of the (b) horizontal and (c) vertical components of the force that the wall exerts on the left end of the beam.

Several students are riding in bumper cars at an amusement park. The combined mass of car A and its occupants is mA = 252 kg. The combined mass of car B and its occupants is mB = 208 kg. Car A is 16 m away from car B and moving to the right at vAi = 2.1 m/s, as shown, when the driver decides to bump into car B, which is at rest. (a) Car A accelerates at 1.5 m/s2 to a speed of 4.9 m/s and then continues at constant velocity until it strikes car B. Calculate the total time for car A to travel the 16 m.
