1.4 m/s im in 12th grade did this so this should be right
HELLO DEAR,
GIVEN:-
MASS (m) = 9000kg
kinetic energy (k) = 18000j
we know :-
k = 1/2 mv²
therefore,
18000 = 1/2 × (9000) × v²
v² =

v² = 36/9
v² = 4
v = 2m/s
hence, option (A) is correct,
I HOPE ITS HELP YOU DEAR,
THANKS

Answer:
13.2 x 10^5 J
Explanation:
Power = work/time
Given
Power = 22kw
= 22 x 1000 = 22000w
Time = 60 secs
Therefore
22000 = work/60
Cross multiply
Work = 22000 x 60
= 1320000
= 13.2 x 10^5J
0.5 swings per second (0.5 swings/sec if you want it shorter)
Answer:
40,000
Explanation:
200x 200=40000
I'm pretty sure that's the answer
Answer:
25m/s
Explanation:
p=mv
75 = 3v
v = 75/3
v = 25 m/s
If you want to verify your answer, just insert the value of v to the equation.
