Displacement = s = v1t +1/2at2
= 0 * 2.05 +1/2*(4.3)*(2.05^2)
= 0 + 9.04
= 9.04 m
Answer: Can't see the graph clearly.
Answer:
9 N
Explanation:
The centripetal force F is F = mrω^2 = (mv^2)/r where m is mass, r is radius of the curve, ω is angular velocity and v is tangential velocity.
In this case, m = 0.5kg, r = 0.5m, v = 3m/s
So F = [0.5kg(3m/s)^2]/0.5m = 9kg-m/s^2 which is 9N
