Abody a of mass 1.5kg, travelling along the positive x-axis with speed 4.5m/s, collides with
another body b of mass 3.2kg which, initially, is at rest. as a result of the collision, a is deflected and
moves with a speed 2.1m/s in a direction which is at angle 30° below the x-axis. b is set in motion at an
angle θ above the x-axis. calculate the velocity of b after the collision.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)

The power exerted by a muscle is the product of the force exerted and the velocity of contraction. the area of which of these shaded regions represents the power exerted while a weight is lifted at maximum speed?
