Answer:
Sam's momentum as he leaves the jump is 1350 kg *m/s.
Explanation:
To solve this problem, we must remember the formula for momentum:
p = mv
Where p represents the momentum of the function, m represents the mass of the object, and v represents the velocity of the object
Now, to solve, we must simply plug in our values into this equation.
p = mv
p = (75 kg)(18 m/s)
p = 1350 kg *m/s
Therefore, your answer is 1350 kg * m/s.

X(OH)₂ + 2HCl = XCl₂ + 2H₂O
n{X(OH)₂}=m{X(OH)₂}/M{X(OH)₂}
n(HCl)=c(HCl)v(HCl)
n{X(OH)₂}=n(HCl)/2
m{X(OH)₂}/M{X(OH)₂}=c(HCl)v(HCl)/2
M{X(OH)₂}=2m{X(OH)₂}/{c(HCl)v(HCl)}
M{X(OH)₂}=2*8.65/{2.50*56.9*10⁻³}=121.6 g/mol
M(OH)=17.0 g/mol
M(X)=121.6-17.0*2=87.6 g/mol ⇒ X=Sr, strontium
Sr(OH)₂ + 2HCl = SrCl₂ + 2H₂O
