In California, changing lanes in the middle of an intersection D. is legal.
Although it is legal, it's not necessarily the safest thing to do in an intersection.
There are two types of flexibility exercises: static stretching, in which you stretch a muscle without moving, and dynamic stretching, which combines stretching with movements.
Answer:
54 J
Explanation:
Kinetic energy is:
KE = 1/2 mv²
where m is mass and v is velocity.
Given m = 3 kg and v = 6 m/s:
KE = 1/2 (3 kg) (6 m/s)²
KE = 54 J
