Answer:
100 J
Step-by-step explanation:
Kinetic energy is jointly proportional to mass and the square of the velocity.
KE = 1/2mv²
KE = 1/2(50 kg)(2 m/s)² = 100 J
Juan has a kinetic energy of 100 joules.
Answer:
Rick is correct
Step-by-step explanation:
I cant see Jo's error...but the correct way is this :
-41.71 rounds to -42
-6.03 rounds to -6
so the quotient is : -42/-6 = 7 <==
The graph starts at $75 since the price for call is $50 and 1 hour of work costs $25.
Direct variation is only noticeable at the beginning of the graph after that the function is linear.
I hope the answer helps.
Answer:
The answer is 3.
Step-by-step explanation:
1. You need to substitute the values into the equation
2. You would then have 1/2(4-3(-2))-2
3. Now you have to multiply 3×-2 and you will now have 1/2(4+6)-2
4. Then you have to add what's in the parenthesis and you will have 1/2(10)-2
5. Now multiply 1/2(10) and uou will have 5-2
6. Now subtract 5-2 and that will = 3
