Acceleration = (change in speed)/(time for the change)
Change in speed = (end speed) - (start speed)
Change in speed = (10 m/s) - (20 m/s) = -10 m/s
Time for the change = 5.00 seconds
Acceleration = (-10 m/s) / (5 sec)
<em>Acceleration = -2 m/s²</em>
That's choice-A .
I believe that your acceleration would be 4 m/s
Answer:
125.66 R/s
Explanation:
First 1200 r / min = 20 r/sec
20 r/s * 2pi Radians / r = 40 pi Radians / sec = 125.66 R/s
Answer:
Why are human beings not called autotrophs even if they make their food in
the kitchen?
How does photosynthesis help to maintain the percentage of oxygen and
carbondioxide in the atmosphere?
