Describe the process of nuclear fission and how the famous equation E = mc2 relates to this process.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Acar travels 40m in 8 seconds find the car speed

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.
