7. a pool cue ball moving at 2.1 m/s east collides in a straight line with the eight ball at rest. find the velocity of the eight ball after the collision if momentum is conserved and
a. the cue ball stops. (5 points)
b. the cue ball continues on in the same direction at 0.10 m/s. (5 points)
c. the cue ball continues on in the same direction at 0.70 m/s. (5 points)

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

On a hot saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 22degreesc. at noon the air conditioner is turned off, and the people go home. the temperature outside is a constant 33degreesc for the rest of the afternoon. if the time constant for the building is 4 hr, what will be the temperature inside the building at 4 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? at 6 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? when will the temperature inside the building reach 24degreesc? 324281
