Question

A professional baseball player can pitch a baseball with a velocity of 44.7 m/s towards home plate. If a baseball weighs 1.4 N, how much momentum does it have when it hits the catcher’s mitt?

Answer 1

Explanation:

weight = 1.4 N

we need to calculate mass first,

mass = weight / g

mass = 1.4 / 9.8

= 0.142 kg

momentum = mass × velocity

momentum = 0.142 × 44.7

momentum = 6.3474 kg m/s

Answer 2

The answer is 6.258 Kgm/s

GIVEN

A professional baseball player can pitch a baseball with a velocity of 44.7 m/s towards home plate.The baseball weighs 1.4 N.

TO FIND

Momentum.

SOLUTION

The above problem can be simply solved as follows;

Weight of baseball = 1.4N

Mass = weight/mass

= 1.4/9.8

= 0.14 kg

Formula to calculate momentum (p) = mv

p = 0.14 × 44.7

= 6.258 Kgm/s

Hence, The answer is 6.258 Kgm/s
