Calculate the magnitude of the linear momen- tum for each of the following cases
a) a proton with mass 1.67 × 10−27 kg mov- ing with a velocity of 6 × 106 m/s.
Answer in units of kg · m/s.
what is mass*velocity ?
To calculate the magnitude of linear momentum, we can use the formula:
Linear Momentum = mass × velocity
In this case, we are given the mass of a proton as 1.67 × 10^(-27) kg and its velocity as 6 × 10^6 m/s.
To find the linear momentum, we multiply the mass of the proton by its velocity:
Linear Momentum = (1.67 × 10^(-27) kg) × (6 × 10^6 m/s)
Now, we can calculate the product:
Linear Momentum = 10^(-27) kg × m/s × 6 × 10^6
To simplify the expression, we can multiply the coefficients:
Linear Momentum = 10^(-27) × 6 × 10^6 kg × m/s
When multiplying numbers expressed in scientific notation, we add the exponents:
Linear Momentum = 6 × 10^(-27 + 6) kg × m/s
Linear Momentum = 6 × 10^(-21) kg × m/s
So, the magnitude of the linear momentum of the proton is 6 × 10^(-21) kg · m/s.
