Answer:
a 10 kg elephant moving at 1 m/s
Explanation:
because kinetic energy depend on how fast an object moves and also depend on the gravitational force which include the weight.
Answer:
The answer is 10Nm
Explanation: I ended up just messing around with the numbers, I multiplied 5 and 2 got 10 as my answer and it was right.
Answer:
0.84
Explanation:
m = Massa balok
g = Percepatan gravitasi
= Sudut kemiringan
= Koefisien gesekan statik antara balok dan bidang miring
Gaya balok karena beratnya diberikan oleh

Gaya gesekan diberikan oleh

Kondisi dimana balok mulai bergerak adalah ketika gaya balok akibat beratnya sama dengan gaya gesek pada balok.

Koefisien gesekan statik antara balok dan bidang miring adalah 0.84.
Explanation:
Below is an attachment containing the solution.
Answer: 585 J
Explanation:
We can calculate the work done during segment A by using the work-energy theorem, which states that the work done is equal to the gain in kinetic energy of the object:

where Kf is the final kinetic energy and Ki the initial kinetic energy. The initial kinetic energy is zero (because the initial velocity is 0), while the final kinetic energy is

The mass is m=1.3 kg, while the final velocity is v=30 m/s, so the work done is:
