Answer:
Sam will do 1152 J of work to stop the boat
Explanation:
Work: This is defined as the product of force and distance, the S.I unit of work is Joules. At any point in science, during calculation Energy and worked can be interchange because they have the same unit.
E = W = 1/2mv²................ Equation 1
Where E = energy, W = work, m = mass, v = velocity.
Given: m = 900 kg, v = 1.6 m/s
Substituting these values into equation 1
W = 1/2(900)(1.6)²
W = 450×2.56
W = 1152 J.
Therefore Sam will do 1152 J of work to stop the boat
Answer:
can someone tell me the answer plz I'm in a rush
The correct answer is C. Since that really was a tricky question I made sure it was correct by checking on Google. Hope I helped! - Amber
The product of wavelength and frequency is always the
speed of the wave.
For this particular wave,
Speed = (2 meters) x (6 per second) = 12 meters per second .
