Acrew member is walking on a tugboat that is pulling a barge. the tugboat is moving at a constant speed upstream in a river that has a constant downstream current. the velocity of the crew member with respect to the tugboat is v 1 . what is the vlocity of the crew member with respect to the barge?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
