Look up pulleys problem through Khan academy and a video should pop up with a problem similar and you should be able to walk through it .
F = ma
So if you want the "a" to stay constant (as it is then uniform acceleration), the F must also be constant to apply a constant force.
2 is the answer
Hello!!
For the maximum height the final velocity is zero, <u>because can't up more.</u>
Then, use the formula:
V = Vi + gt
Replacing, we have:
0 m/s = 5,3 m/s + (-9,8 m/s² * t)
0 m/s - 5,3 m/s = -9,8 m/s² * t
(-5,3 m/s) / -9,8 m/s² = t
t = 0,54 s
The time it will take to reach the maximum height is <u>0,54 seconds.</u>
Answer:
A
Explanation:
the answers are all not good, but I would say A is the best
