Answer:
Approximately .
Explanation:
At a speed of , the kinetic energy of the ride and the riders of mass (combined) would be:
.
If friction is negligible, would be the work required to achieve this speed. That is:
.
Given that this work was completed in a duration of , the average power would be:
.
Substitute in , , and :
.
(Note that if acceleration is constant, the power input to the ride would be proportional to . The average power of input to the ride would be a quarter of the peak power input. Multiplying average velocity (proportional to ) by average force (proportional to ) would overestimate the average power by .)
Answer:
The minimum speed when she leave the ground is 6.10 m/s.
Explanation:
Given that,
Horizontal velocity = 1.4 m/s
Height = 1.8 m
We need to calculate the minimum speed must she leave the ground
Using conservation of energy
Put the value into the formula
Hence, The minimum speed when she leave the ground is 6.10 m/s.
The answer to this question is 2400Hz
Answer:
<u />
Explanation:
Given:
- mass of particle A,
- mass of particle B,
- mass of particle C,
- All the three particles lie on a straight line.
- Distance between particle A and B,
- Distance between particle B and C,
Since the gravitational force is attractive in nature it will add up when enacted from the same direction.
<u>Force on particle A due to particles B & C:</u>
