Homework Statement
An electron has momentum of magnitude 2.74 10-22 kg · m/s. What is the electron's speed?
Homework Equations
p=ymv, where y=gamma
The Attempt at a Solution
v=p/m, which is wrong. Any suggestions?
If p = γmv, then v = p/γm not p/m. Of course, γ itself is a function of v, so you need to write it out and then solve for v correctly.psilovethomas said:Homework Statement

Momentum is a physical quantity that describes the motion of an object. It is defined as the product of an object's mass and its velocity.
The formula for calculating momentum is p = m * v, where p is momentum, m is mass, and v is velocity.
Momentum is directly proportional to the speed of an electron. This means that as the speed of an electron increases, its momentum also increases.
The speed of an electron can be calculated by dividing its momentum by its mass. The formula is v = p / m, where v is speed, p is momentum, and m is mass.
The unit of measurement for momentum is kilogram meters per second (kg*m/s) in the SI system. In other systems, it may be measured in grams centimeters per second (g*cm/s) or pound feet per second (lb*ft/s).
