- A boat with a still water velocity of 20.0km/hr heads North across a river that flows directly East at 12.0km/hr. ( I am in need of help with d & e). a) What will be the resultant velocity of the boat if it does not fight the current ? (23.3 km/hr 31.0o E of N) b) If the river is 700.m wide, how long will it take the boat to reach the opposite side if it does not fight the current ? (.035hr) c) How far downstream, relative to the bank, will the boat be carried if it does not fight the current ? (.420km or 420.m) d) What must be the heading of the boat if it is to keep a path directly North across the stream ? Draw a vector diagram. e) How long will it take the boat to cross the stream if it keeps its heading during the entire trip ?A boy throws a baseball onto a roof and it rolls back down and off the roof with a speed of 4.30 m/s. If the roof is pitched at 20.0°below the horizon and the roof edge is 4.10 m above the ground, find the time the baseball spends in the air and the horizontal distance from the roof edge to the point where the baseball lands on the ground. (a) the time the baseball spends in the air (in s) (b) the horizontal distance from the roof edge to the point where the baseball lands on the ground (in m)Please see att
- Starting from the relative position shown, aircraft B is to rendezvous with the refueling tanker A. If B is to arrive in close proximity to A in a 2.3-minute time interval, what absolute velocity vector should B acquire and maintain? The velocity of the tanker A is 306 mi/hr along the constant-altitude path shown. 8960 A 2710' В Answer: VB = ( i i+ i j) mi/hrA plane departs from Toronto and heads to Ottawa travelling at 529.9 km/h [N33.67°E, relative to the ground]. If the plane experiences a jet stream of 177.9 km/h [W, relative to the ground] during the trip, calculate the velocity of the plane with respect to the jet stream.Show that the girl at A can throw the ball to the boy at B by launching it at equal angles measured up or down from a 45° inclination. If va = 10 m/s, determine the range R if this value is 15°, i.e., 01 = 45° – 15° = 30° and 02 = 45° + 15° = 60°. Assume the ball is caught at the %3D same elevation from which it is thrown.
