A cruise ship moves southward in still water at a speed of 20.0 km/h, while a passenger on the deck of the ship walks toward the east at a speed of 5.0 km/h the passenger's velocity with respect to earth is

a) 20.6 km/h at an angle of 14.04° east of south.
b) 20.6 km/h at an angle of 14.04° south of east.
c) 25.0 km/h south.
d) 20.6 km/h east.
e) 20.6 km/h south.

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

Amodel rocket with a mass of 0.212 kg is launched into the air with an initial speed of 84 m/s. how much kinetic energy will the rocket have at a height of 214 m? assume there is no wind resistance. 634 j 303 j

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
