A river flows due south with a speed of 2.8 m/s. A man steers a motorboat across the river; his velocity relative to the water is 4.9 m/s due east. The river is 600 mm wide. a-What is the magnitude of his velocity relative to the earth? b-What is the direction of his velocity relative to the earth? c-How much time is required to cross the river? d-How far south of his starting point will he reach the opposite bank?

a guy is throwing pumpkins off a five story (15 meters high) building and wants the messiest result possible (highest velocity impact). a) he first throws a pumpkin downward at 45 degrees below the horizon at 15 m/s. how fast does the pumpkin hit the ground? at what angle does it hit? b) he then throws a second pumpkin upward with the same velocity 45 degrees above the horizon. how fast does the second pumpkin hit the ground? c) which strategy (throwing the pumpkin up or down) results in a higher velocity impact? think about why this might be

An Alaskan rescue plane drops a package of emergency rations to a stranded party of explorers. If the plane is traveling east at 40 m/s and is 100 meters above the ground: a.Using the release point as the origin, find the time it takes for the package to reach the ground once released. b.How far east of the release point does the package strike the ground? Also, What is the speed of the package as it hits the ground? c.With what angle (below the horizontal) does the pack strike the ground? Please show work for all of the parts.

A projectile is thrown from the top of a 50m building with an initial speed of 10m/s and an angle of 35 degrees. Calculate the time to reach the ground and the velocity just before it strikes the ground.
Sheena can row a boat at 3.20 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.80 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head upstream at an angle of 25.0° from the direction straight across the river. a.)What is her speed with respect to the starting point on the bank? b.)How long does it take her to cross the river?
A ball is thrown at an initial height of 65 feet at an initial velocity of 75 feet/second at an angle of 65 degrees. Given the parametric equations yY = - - 16t + Vo · Sin(0)t + ho and x = Vo Cos(0)t. When doing calculations, carry 5 digits of accuracy, so your round off does not build up. a. What is the ball's height in 3 seconds? feet. seconds. b. When will the object hit the ground? feet. c. How far horizontally will the ball be when it hits the ground? seconds. d. When will the ball be at its maximum height? e. What is the ball's maximum height? feet. feet f. How far horizontally will the ball be when it reaches its maximum height?
1) A student drove to the university from her home and noted that the odometer reading of her car increased by 15.8 km. The trip took 25.9 min. a) What was her average speed, in meters per second? b) If the straight-line distance from her home to the university is 10.3 km in a direction 25° south of east, what was the magnitude of her average velocity in meters per second? c) If she drove back home using the same path she took out to the university and arrives 7.9 h after she first left home, what was her average speed for the entire trip, in meters per second?
