Explain the relationship between distance and time in terms of an object's speed.

Dźwig podniósł kontener o masie m = 80 kg na wysokość h = 10 m. Pierwsze 5 m kontener przebył z przy- spieszeniem o wartości a = 1 m/s2, a następne 5 m - ruchem jednostajnym. Przyjmij, że g = 10 m/s2.

Leaving the distance between the 97 kg and the 548 kg masses fixed, at what distance from the 548 kg mass (other than infinitely remote ones) does the 69.7 kg mass experience a net force of zero?

A proton moving at 8.00 106 m/s through a magnetic field of magnitude 1.72 T experiences a magnetic force of magnitude 7.20 10-13 N. What is the angle between the proton's velocity and the field? (Enter both possible answers from smallest to largest.

If an object moves in uniform circular motion in a circle of radius R = 1.0 meter, and the object takes 4.0 seconds to complete ten revolutions, calculate the magnitude of the velocity around the circle.
