Answer:
c. increase momentum
Explanation:
When cars bounce off each other, or rebound, there is a larger change in momentum and therefore a larger impulse. A larger impulse means that a greater force is experienced by the occupants of the cars. When cars crumple together, there is a smaller change in momentum and therefore a smaller impulse.
8.05 that is the answer lllllllll
Answer:
The answer to your question is W = 3695464.4 J
Explanation:
Mechanical work is the force applied to an object multiply by the distance this object move as a consequence of the force.
Formula
Work = W (J)
Force = F (N)
distance = d (m)
W = F x d
Substitution
F = 6818.2 N
d = 542 m
W = 6818.2 x 542
Simplification and result
W = 3695464.4 J
Given that:
μ = 36
<span>σ = 3
</span>
<span>Standardize x to z = (x - μ) / σ </span>
<span>P( 39 < x < 42) = P[( 39 - 36) / 3 < Z < ( 42 - 36) / 3] </span>
<span>P( 1 < Z < 2) = P( x < 2) - P( x < 1)
= 0.9772 - 0.8413
= 0.1359 </span>
<span>(0.1359)(30)
= 4.0777
= 4 days</span>
Yes, you need to convert unless the question specifically requires km/h.
