After a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by v=1.2i9.8tj where v is in meters per second and t is in seconds. The balls displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by r=00.3803vdt To perform the integral, you can use the calculus theorem [A+Bf(x)]dx=Adx+Bf(x)dx You can think of the units and unit vectors as constants, represented by A and B. Perform the integration to calculate the displacement of the ball from the edge of the table at 0.380 s.

Two very hungry (and competitive) pre-med students suddenly see a parked ice cream truck that is that is down to its last ice cream cone. The truck is a distance of D meters away from the nearest student, who runs toward the truck at 2.5 m/s, and the second student (who was a track star in high school) runs toward it faster at 5.7 m/s but the second student is 10.0 meters farther away (to where he has to run D+10.0 m). What is the maximum possible value of D for the two students to reach the ice cream truck at the same time?

Two small spacecraft, each with a mass m = 2000 kg, are in orbit circular Earth, at an altitude h of 400 km. Igor, the commander of one of the ships, arrives at any fixed point in orbit 90 s ahead of Picard, the commander of the other ship. What are the (a) periods T0 and (b) the speed v0 of the ships? At point P, Picard shoots an instantaneous burst in the forward direction, slowing your ship by 1.00%. After this explosion, the elliptical orbit follows, which is shown discontinuous in the figure. What are (c) the kinetic energy and (d) the potential energy of your ship immediately after the explosion? In Picard's new elliptical orbit, what are (e) the total energy E, (f) the semi-major axis a, and (g) the orbital period T? (h) How long before Igor will return Picard to P? Since you can only ansewer to 3 sub-parts, I'll ask here (a,b,c) and submit another question for (d,e,f), (g,h). Thanks.

I had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?
