You could change your velocity by altering both your speed and direction.

For example, if you are running north at 10 miles per hour, and turn into a street going east, then slow down to 5 miles per hour, you would have changed your velocity.

A baseball has a momentum of 6.0 kg m/s south and a mass of 0.15 kg. What is the baseball’s velocity? Show work

kupik [55]

Momentum of an object is defined as product of mass and velocity

so it is given as

$P = m* v$

here it is given that

mass = 0.15 kg

momentum = 6 kg m/s

so by plug in values in the above equation

$6 = 0.15 * v$

$v = \frac{6}{0.15}$

$v = 40 m/s$

so its speed will be 40 m/s
