Racing Racing Cars A and B are traveling on circular portions of a racetrack. In the instant shown, the speed of A is decreasing auto rate of
Block A in the fig. 5.58 weighs 1.20N and Block B weighs3.60N. The Coefficient of kinetic friction between all surfaces is0. 300. Find the magnitude of the horizontal force F necessary to drag black B to the left at a constant speed a) if A rest on B and moves with it (fig. 5.28am). b) If A is held at rest.
On a long flat firing range, a projectile is fired with an initial speed of 75.2 m/s at an angle of 34.5 degrees above the horizontal. Determine (a) the maximum height reached by the projectile, (b) the total time in the air, (c) the total horizontal distance covered (that is, the range) and (d) the velocity of the projectile 1.50 s after firing.
Sometimes students that seek algebra assistance come from non-Math subjects where logic and irrational numbers problems should be solved.
