Answer:
The kinetic energy of the roller coaster is 1600000 J.
Step-by-step explanation:
Given:
Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.
Now, we need to find the kinetic energy of the roller coaster.
So, Mass of roller coaster (m) = 8000 N.
Velocity of roller coaster (v) = 20.0 m/s.
Now, putting the formula of kinetic energy:
Therefore, the kinetic energy of the roller coaster is 1600000 J.
Answer:
m∠A ≈ 39.865°
Step-by-step explanation:
C² = 16² + 15² - 2 × 16 × 15 × cos (97°)
=> C = 23.22708085
sin (97°)/23.22708085 = sin A/15
=> sin A = sin (97°) × 15/23.22708085
=> A = (sin (97°) × 15/23.22708085)
=> A ≈ 39.865
