2. Work occurs when (2 points) O an applied force results in movement of an object in the same direction as the applied force
O
an object is subjected to balanced forces resulting in movement of the obiect

the energy present is the result of the force acting on the object
Ο Ο
the movement of the object was caused by a force and is in the opposite direction of the force

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.

How is the ideal mechanical advantage of a wheel and axle calculated?

Aforce of 8,480 n is applied to a chart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?
