D you only need that much
It would be 1. You add all the temperatures. Get the sum and divide it by the amount of temperatures.
It can be turned into 4•19/81 (mixed proper fractions) or in decimal 4.2346 (4dp)
i believe the answer would be A.
in slope-intercept form, it's y = -3/2x - 1
Answer:
288J
Step-by-step explanation:
recall the formula for kinetic energy
KE = (1/2) mv²
where m is the mass (= 4kg) and v is the velocity(=12 m/s)
hence
KE = (1/2) (4)(12)² = 288J
