6. A student throws his worthless lab partner off speed of 10 m/s a. How long does it take the deadbeat to hit t

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

How can you increase the strength of an electromagnet?

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.
