Explanation:
Answer:
(A) The acceleration of Melissa is 0.211 m/s²
(B) The net force on Melissa is 9.5 N
Explanation:
Given;
radius of the carousel, r = 8.0 m
speed of Melissa, v = 1.3 m/s
mass of Melissa, m = 45 kg
(A) The acceleration of Melissa is given by centripetal acceleration;

(B) The net Force on Melissa is given by centripetal force;

Answer:
p=mv=(813kg)(17)= 13,821 kg m\s
The force applies an acceleration in the reverse direction of
29 N = (0.145 kg) <em>a</em> → <em>a</em> = 200 m/s²
and in order to hit the ball back with speed 40.0 m/s, this acceleration is applied over time <em>t </em>such that
200 m/s² = (40.0 m/s - (-40.0 m/s)) / <em>t</em> → <em>t</em> = (80.0 m/s) / (200 m/s²) = 0.4 s
