physics (speed of plane by radar)
The radar stations A and B, separated by the distance a = 500 m, track the plane C by recording the angles α and β at 1-second intervals, If three successive readings are shown in the table,calculate the speed v of the plane and the climb angle y at t = 10 seconds as...

Okay so I have a 1/2 in thick ellipsoidal steel plate where (p=493 lb/ft^3) and it has a major axis diameter of 4ft and a minor of 2ft. the plate rolls w/out slipping (friction=0.15) and in a vertical position has an angular velocity of of w=4 rad/s(i.e. the 4 ft diameter is a...

A golfer takes two putts to get his ball into the hole once he is on the green. The first putt displaces the ball 8.10 m east, the second 6.00 m south. What displacement would have been needed to get the ball into the hole on the first putt?

A Chinook (King) salmon (Genus Oncorynchus) can jump out of water with a speed of 5.95 m/s. (See Problem 4.9, page 111 for an investigation of how the fish can leave the water at a higher speed that it can swim underwater.) If the salmon is in a stream with water speed equal t...
