The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.
To solve for p, plug in 750 kg for mass and 30 m/s for velocity. • is a multiplication symbol
p = mv
p = 750kg • 30m/s
p = 22500 kg•m/s
Use the inverse square law, thus if you move a distance of 3m away, the sound intensity decrease by 1/3^2= 1/9
Answer:
76.1N
Explanation:
Given parameters:
Mass of the ball = 7.77kg
Unknow:
Weight of balloon = ?
Solution:
Weight is the vertical force applied on a body.
Weight = mass x acceleration due gravity
So;
Weight = mass x acceleration due to gravity
So;
Weight = 7.77 x 9.8 = 76.1N
