Answer:
60 000 J
Explanation:
The PE will be converted to KE entirely (if the lowest point is ground level)
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.
I think the correct answer from the choices listed above is option B. If asked to describe a wave, you could say waves are the continuous transmission of energy from one location to the next. <span>In physics, a </span>wave<span> is an oscillation accompanied by a transfer of energy that travels through a medium. Hope this helps.</span>
Weight = (mass) x (gravity)
Divide each side by (gravity): Mass = (weight) / (gravity) =
(55.54 N) / (9.83 m/s²) =
5.65 kilograms
1.25m/s'2 by the first eq of motion
