Answer:
-0.8 m/s²
Explanation:
Acceleration is the slope of a velocity vs. time graph.
a = Δv / Δt
a = (0 m/s − 12 m/s) / (15 s − 0 s)
a = -0.8 m/s²
Net centripetal force is given by the product of mass and centripetal acceleration
Here we know that
mass (m) = 20 kg
speed (v) = 10 m/s
radius (R) = 15 m
So here we can say that centripetal acceleration is given as
now from the formula of force
<em>so correct answer would be 133 N</em>
Answer:
0.2m
