Answer:
The skier’s speed on the two level stretches are 22.13 m/s and 27.29 m/s.
Explanation:
Given that,
Slope down = 32°
Height = 25 m
Before leveling,
Slope down = 20°
Height = 38 m
We need to calculate the skier’s speed on the two level stretches
Using formula of energy
For first stretch,
Height = 25 m
Put the value into the formula
For second stretch,
Height = 38 m
Put the value into the formula
Hence, The skier’s speed on the two level stretches are 22.13 m/s and 27.29 m/s.
Answer:
19372.29 N
Explanation:
Kinetic Energy of the man = Work done by the average resistive force of water.
mg(H+d) = F×d............................ Equation 1
where, m = mass of the woman, H = Height of the platform, d = depth of water reached, F = average resistive force exerted by water.
make F the subject of the equation,
F = mg(H+d)/d...................... Equation 2
Given: m = 65.0 kg, H = 10 m, d = 3.4 m, g = 9.8 m/s²
Substitute into equation 2
F = 65(9.8)(100+3.4)/3.4
F = 19372.29 N
