You know the power for a machine and the time it takes to produce that power, what value can you calculate?

What is the major limitation to the light microscope?

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
