a) what is the momentum of a 4.6 kg baseball moving at 1.4 m/s?
b) a child is running with a velocity of 4.5 m/s and has a momentum of 120 kgm/s. What is the child's mass?
~formula~
P=mv
help please!!!
a) momentum is the product M*V
b) Divide the momentum by the speed
To calculate momentum, you can use the formula P = mv, where P represents momentum, m represents mass, and v represents velocity.
a) To find the momentum of a 4.6 kg baseball moving at 1.4 m/s, you can substitute the given values into the formula.
P = m * v
P = 4.6 kg * 1.4 m/s
P = 6.44 kg⋅m/s
b) To determine the mass of a child running with a velocity of 4.5 m/s and having a momentum of 120 kg⋅m/s, you need to rearrange the formula to solve for mass (m).
P = m * v
m = P / v
m = 120 kg⋅m/s / 4.5 m/s
m = 26.67 kg
So, a) the momentum of the baseball is 6.44 kg⋅m/s, and b) the child's mass is approximately 26.67 kg.
