A student drives 10 km to the north and then 20 km 30 degrees S of E. By using the component method, what are the magnitude and direction of his displacement from the starting point?
A basketball player who is 2.00 m tall is standing on the floor 10.0 m from the basket as in figure. If he shoots the ball at a 40.0° angle with the horizontal at what initial speed must he throw so that it goes through the hoop without striking the backboard? the basket height is 3.05 m.
A rugby player runs with the ball directly toward his opponent’s goal, along the positive direction of an x axis. He can legally pass the ball to a teammate as long as the ball’s velocity relative to the field does not have a positive x component. Suppose the player runs at speed 4.0 m/s relative to the field while he passes the ball with velocity relative to himself. If has magnitude 6.0 m/s, what is the smallest angle it can have for the pass to be legal?
As a projectile moves in its parabolic path, where are the velocity and acceleration vectors perpendicular to each other? (a) Everywhere along the projectile’s path, (b) at the peak of its path, (c) nowhere along its path, or (d) not enough information is given.
In the Mississippi river banks in Louisiana, a tug boat leaves a harbor and sails 5.0 km in the direction 45 degrees south of east, where the captain stops to pick up a small load of crabs. A short time later, the boat sails 1.0 km in the direction west. What is the magnitude and direction of the resultant displacement from the harbor?
A man points his rowboat north, straight across a river of width 114.3 m. The river flows due east. The man starts across, rowing steadily at 0.90 m/s @ north and reaches the other side of the river at a point 207 m downstream from his starting point. What is the speed of the river?
In the figure, a ball is launched with a velocity of magnitude 7.00 m/s, at an angle of 41.0° to the horizontal. The launch point is at the base of a ramp of horizontal length d1 = 6.00 m and height d2 = 3.60 m. A plateau is located at the top of the ramp. Does the ball land on the ramp or the plateau? When it lands, what are the magnitude and angle of its displacement from the launch point?
