You are working out on a rowing machine. each time you pull the rowing bar (which simulates the oars) toward you, it moves a distance of 1.3 m in a time of 0.95 s. the readout on the display indicates that the average power you are producing is 85 w. what is the magnitude of the force that you exert on the handle

What happens to an isotope during radioactive decay?

Aforce of 100 newtons is used to move an object a distance of 15 meters with a power of 50 watts. find the work dine and the time it takes to do the work

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.
