k = 1/2 × m × v^2
_____________________________
1. k = 1/2 × 60 × ( 10 )^2
k = 30 × 100
k = 3000 j
_____________________________
2. k = 1/2 × 60 × ( 9 )^2
k = 30 × 81
k = 2430 j
_____________________________
3. k = 1/2 × 60 × ( 4 )^2
k = 30 × 16
k = 480 j
_____________________________
4. k = 1/2 × 60 × ( 6 )^2
k = 30 × 36
k = 1080 j
______________________________
5. k = 1/2 × 60 × ( 0 ) ^2
k = 30 × 0
k = 0 j
D would be the answer because The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Cells.
When you have a group of similar cells, you make tissues. This is like having many specialized muscle cells grouping together to make a muscle tissue that can then make something like a bicep. <span />
Answer:
EXAMPLE:when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
