D
D
when the pendulum is at the lefend and right end.
0 because kinetic energy is only formed when a moving object is moving.
dont know the others sorry

i got about half way for you hope it correct
give me nothing if you got some wrong!
or just give me a message saying that i didn't help
Answer:
Final speed of the ball, v = 20 m/s.
Explanation:
It is given that,
Initial speed of the ball, u = 40 m/s
Time. t = 2 s
We need to find the speed of the ball after 2 seconds. Let it is denoted by v. It can be calculated using first equation of motion as :

Here, a = -g, as the ball is ball is moving under the action of gravity.


v = 20 m/s
So, the speed of the ball after 2 seconds is 20 m/s. Hence, this is the required solution.
Answer:
A. ls sensitive to heat
this is correct answer
I hope it's helpful for you.......
Por the impulse, use the formula:
I = F * t
Now, we know:
4000 N = 4000 kg*m/s²
Replacing we have:
I = 4000 kg*m/s² * 0,200 s
Resolving:
I = 800 kg.m/s²
The impulse is <u>800 kg.m/s²</u>
Answer:
(a) 98.548 mPa
(b) N = 942346
