Aprojectile proton with a speed of 500 m/s collides elastically with a target proton initially at rest. the two protons then move along perpendicular paths, with the projectile path at 60° from the original direction. (a) what is the speed of the target proton after the collision? 0 incorrect: your answer is incorrect. m/s (b) what is the speed of the projectile proton after the collision?
Answers: 1
, and (b) the speed of the projectile proton after the collision is: 
.
, and y axle:
. Now replacing the value given as: 
, 
for the projectile proton and according to the problem 
are perpendicular so 
, and assuming that 
, we get for x axle:
and y axle: 
, then solving for 
, we get:
and replacing at the first equation we get:
, now solving for 
, we can find the speed of the projectile proton after the collision as:
, that is the speed of the target proton after the collision.Another question on Physics

When you see distant streetlights through smog, they look dimmer and redder than they do normally. but when you see the same streetlights through fog or falling snow, they look dimmer but not redder. use your knowledge of the interstellar medium to discuss the relative sizes of the particles in smog, fog, and snowstorms compared to the wavelength of light.
