What is the final speed of a train which accelerates uniformly at a rate of 0.6m/s from a speed of 2/ms for 30s

What if? physicists often measure the momentum of subatomic particles moving near the speed of light in units of mev/c, where c is the speed of light, and 1 mev = 1.6 ✕ 10−13 kg · m2/s2. based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental si units?

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
