Answer:
900 j
Step-by-step explanation:
KE=1/2mv^2
so:
1/2x(2kg)x(30m/s)^2
is 900 joules. :)
I believe the answer is Monday!
The garden's width is 45. We know this because
(length)
35x2 is 70 and you need to neutralize that by taking away 70 from both sides.
Now divide by 2 on both sides to neutralize the 2 times x.
meaning that leaves us with
91
Follow the order of operations.
3^4 + 2 * 5
81 + 2 * 5 (Exponent)
81 + 10 (Multiplication)
91 (Addition)

If she went 10 miles upstream in the same time as she went 20 miles downstream, that means the downstream speed is twice the upstream speed.
The speed is still water is 9 mph.
The speed of the current is c.
Going downstream, the current adds speed, so the sped downstream is 9 + c.
The speed upstream is 9 - c.
9 + c is twice 9 - c.
9 + c = 2(9 - c)
9 + c = 18 - 2c
3c = 9
c = 3
Answer: The speed of the current is 3 mph.
Check:
9 + c = 12
9 - c = 6
By taking into the account the speed of the current, the downstream speed, 12 mph, is indeed twice the upstream sped, 6 mph.
