6. 'A beach ball is rolling in a straight line toward you at a speed of 0.5 m/s. Its momentum is 0.25 kg*m/s. What is the mass of the beach ball?

Step-by-step explanation:

Momentum is mass times velocity.

p = mv

0.25 kg m/s = m (0.5 m/s)

m = 0.5 kg

i pretty sure it is

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
