Question

A marble with a mass of 1.5 grams rolls at a constant rate of 0.50 cm/s across a table. What is the magnitude of the marbles momentum?

Answer 1

Answer:

Momentum is given by

P = 0.75 gram cm/s

Explanation:

As we know that momentum is defined as product of mass and velocity

$P = mv$

here we know that

m = 1.5 gram

v = 0.50 cm/s

now here we know from the formula

$P = 1.5 \times 0.50$

$P = 0.75 gram cm/s$

Answer 2

P=mv
p=0.0015kg * 0.005m/s 
p=7.5*10^{-6}
