92 percent because you multiply it by 2
Without air resistance, there is no horizontal force on the projectile,
so it has no horizontal acceleration. The answer is "zero".
KE = 0.5mV^2 = 0.5 * 0.0025 * (20)^2 =

It's heavily based on the object's mass...
If you know which object has the most mass than I would choose that one, but personally I think the yellow one has the most mass...
Answer:106.6N
Explanation:
Centripetal force is a force that cause a body to move along a circular path in a field. The body possesses a mass and velocity(since it's moving) and also radius alone the circular path on which it moves.
Given mass (m) = 2kg, velocity (v) = 8m/s and radius (r) = 1.2m
Centripetal acceleration(a)= v²/r
Centripetal force = ma = mv²/r
Substituting this values in the formula above we have;
Centripetal force = 2×8²/1.2m
Centripetal acceleration = 128/1.2
= 106.6N
