Answer:
14,653 J.
Explanation:
We know that,
Total mechanical energy is equal to the sum of all the potential and kinetic energies.
Given,
Kinetic energy when a car jumps off a ramp= 5000 J
Potential energy = 4685 J
Potential energy when the car lands= 4968 J
TME = 5000 + 4685 + 4968
= 14,653 J
Hence, the car's total mechanical engery is equal to 14,653 J.
Answer:
1109m
Explanation:
The distance h₁ traveled by the rocket during acceleration:
The velocity v₁ at this height h₁:
When the rocket runs out of fuel, energy is conserved:
Solving for h₂:
