A stone weighing 0.5 kg was thrown at a speed of 10 m / s at an angle of 60 degrees to the horizon. What is the power developed by gravity at the top of the trajectory? Acceleration of gravity 10 m / s2.

Acar moves a distance of 50.0 km west, followed by a distance of 64.9 km north what was the magnitude of the displacement of the car, in units of kilometers?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Decreased sensitivity to an unchanging stimulus is known as
