The barrel of a rifle has a length of 0.855 m. a bullet leaves the muzzle of a rifle with a speed of 553 m/s. what is the acceleration of the bullet while in the barrel? a bullet in a rifle barrel does not have constant acceleration, but constant acceleration is to be assumed for this problem. answer in units of m/s 2 .

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false

The energy equivalent of the rest mass of an electron is

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.
