A ship is 2.2° off course. If the ship is traveling at 28.0 miles per hour, how far off course will it be after 7 hours?

A boat whos speed in still water is 5.0m/s headed west across a river. The river current is 2.5m/s south. If the river is 2395 wide, how long does it take the boat to cross the river.

An airplane heads northeast at an airspeed of 700 km/hr, but there is a wind blowing from the west at 30 km/hr. In what direction does the plane end up flying? Give the angle relative to north and to one decimal place. degrees What is its speed relative to the ground? Round your answer to nearest integer. km/hr

A plane is flying at a speed of 320 miles per hour on a bearing of N65°E. Its ground speed is 390 miles per hour and its true course, given by the direction angle of the ground speed vector, is 30°. Find the speed, in miles per hour, and the direction angle, in degrees, of the wind. The speed of the wind is miles per hour. (Do not round until the final answer. Then round to the nearest tenth as needed.)

2 sig figs. Answer in degrees. Put north in the direction of positive y, and East in the direction of positive x.

A ship sets out to sail to a point 142 km due north. An unexpected storm blows the ship to a point 130 km due east of its starting point. (a) How far and (b) in what direction (as an angle from due east, where north of east is a positive angle) must it now sail to reach its original destination?

A sailboat sets out from the U.S. side of Lake Erie for a point on the Canadian side, 89.0 km due north. The sailor, however, ends up 43.0 km due east of the starting point. (a) How far must the sailor now sail to reach the original destination? (b) In what direction must she sail? (counterclockwise from due east)

Hiker Harry walks 4 km east then 7 km 25o north of west. What is the magnitude and direction of Harry’s position after his hike as measured from his starting point? Give the angle measured relative to east. For example 90° means directly north.

On a roller coaster ride the total mass of a cart - with two passengers included - is 268 kg. Peak K is at 43.2 m above the ground and peak L is at 26.0 m. At location K the speed of the cart is 17.2 m/s, and at location L it is 12.5 m/s. (The wheel mechanism on roller coaster carts always keeps the carts safely on the rail.) K How much mechanical energy is lost due to friction between the two peaks? Submit Answer Tries 0/10
