An object disintegrates into two fragments. One of the fragments has mass 1.00 MeV/c 2 and momentum 1.75 MeV/c in the positive x direction. The other fragment has mass 1.50 MeV/c 2 and momentum 2.005 MeV/c in the positive y direction. Find (a) the mass and (b) the speed of the original object.

What is a possible result of higher air temperature caused by global warming

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
