When the mass of a body increases, the momentum will decrease True False
The figure shows a right-angled construction frame ABC. When measured at rest, it has dimensions as follows: AB = 18.9 m, AC = 10.0 m, and BC = 16.0 m. This frame is now given a new velocity of 0.420 c, relative to Earth, in a direction parallel to AC. How long is part BC of this frame with the new velocity as measured by Earth-based engineers?
The ABC lift is at rest. You want to estimate the momentum that ABC exerts in C if the weight of A is 105 kg. AB is 12.15 m and weighs 400 kg, BC is 2.7 m and weighs 150 kg. Approximate AB and BC as evenly thick everywhere and homogeneous. Point A is 13.5 m above C in height and B is 2,025 m above C in height. A) What is the moment of force that ABC exerts in C if positive value is counterclockwise in the image? B) If AB instead weighs 150 kg and BC weighs 400 kg, but all other quantities are the same, calculate the torque in C.What is the moment of force that ABC exerts in C with these masses, if positive value is counterclockwise in the picture?

1. A surge is moving at 9 f t/s into a basin of depth 1.4 f t where the speed is zero. Find the water depth behind the surge and the drift velocity behind the surge (that is, the velocity downstream of the surge in a stationary frame of reference). 2. A river of depth 2 m flows downstream at 1 m/s. A surge of depth H moves up the river at 5 m/s relative to a stationary observer on the bank of the river. Find H.
