A police officer w/a radar gun is parked 20 feet off of the highway. The radar gun reads 75 mph when the car is 100 feet from the police car (as measured along the highway). what is the actual speed of the car? I'm not sure how to set up the problem. Will the actual speed be less than or greater than 75? What does the probl

A motorboat going downstream overcome a raft at a point A; t = 60 min later it turn back and after some time passed the raft at a distance 6.0 km from the point A. Find the flow velocity assuming the duty of the engine to be constant.
Please see the attachments. In solving use the coriolis accel concept and i j k vector coordinates. 15.148 and 15.149 Pin P is attached to the wheel shown and slides in a slot cut in bar BD. The wheel rolls to the right without slipping with a constant angular velocity of 20 rad/s. Knowing that x = 480 mm when theta = 0, d
A 1.2-lb block B slides without friction inside a slot cut in arm OA which rotates in a vertical plane at a constant rate, theta = 2 rad/s. At the instant when theta = 30 degrees, r = 2 ft and the force exerted on the block by the arm is zero. Determine, at this instant, (a) the relative velocity of the block with respect to the
How can I solve this problem below: At t=0, wedge A starts moving to the right with a constant acceleration of 100 mm/s^2 and block B starts moving along the wedge toward the left with a constant acceleration of 150 mm/s^2 relative to the wedge. Determine the acceleration of block B. The answer for verification is 80.7 mm
The ski boat's jet propulsive system draws water in at point A (at the middle of the bottom of the boat) and expels it at B (at back of boat) at 80ft/s relative to the boat. Assume that the water drawn in enters with no horizontal velocity relative to the surrounding water. The maximum mass flow rate of water through the engin
It's a sunny Sunday afternoon, about 17 degrees and you are walking around a lake enjoying the early signs of spring. The sidewalk is crowded with runners and walkers. You notice a runner approaching you wearing a t-shirt with writing on it. You read the first two lines, but are unable to read the third and final line before he
