Avolleyball starts from rest and accelerates with an acceleration of 0.415 m/s2 while moving down a 9.00 m long inclined plane. when it reaches the bottom, the ball rolls up another plane, where, after moving 14.50 m, it comes to rest.
a) what is the speed of the ball at the bottom of the first plane?
m/s
b) how long does it take to roll down the first plane?
s
c) what is the acceleration along the second plane?
m/s2
d) what is the ball's speed 8.25 m along the second plane?
m/s

What would be the result of an alpha particle coming into a magnetic field? a) the alpha particle will stop moving. b) the alpha particle will reverse its direction. c) the alpha particle will be deflected in a curve path. d) the alpha particle will continue to travel in a straight line.

A1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. what is the magnitude of the friction force required to keep the car from sliding?

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
