Answer:
Explanation:
As we know that bullet + pendulum system will move to the height of 0.650 m above the initial position
so here we can use energy conservation to find the speed just after the bullet hit the block
Now we can use momentum conservation to find the initial speed of the bullet
The surface of the table and brick may not match up perfectly. This means that friction may occur leading to the brick slowing down or some bit of heat resulting from the contact.
Answer:
On a distance time graph, the distance will always be the dependent variable on the y- axis. Time is the independent variable and will always be placed on the x-axis. The lines on the graphs can tell you many different things.
Explanation:
Answer:
7.5 m/s²
Explanation:
Given:
v₀ = 0 m/s
v = 30 m/s
t = 4 s
Find: a
v = at + v₀
(30 m/s) = a (4 s) + (0 m/s)
a = 7.5 m/s²
Answer:
- Waves with higher amplitude transfer HIGHER energy.
- Waves with higher frequency transfer HIGHER energy.
