Answer:
4.5m/s
Explanation:
Given parameters:
Mass of object = 31kg
Net force = 25N
radius = 25m
Unknown:
Velocity = ?
Solution:
To solve this problem, we must understand that the net force here is a centripetal force.
F = [tex]\frac{mv^{2} }{r}[/tex]
F is the centripetal force
m is the mass
v is the velocity
m is the mass
25 = [tex]\frac{31 x v^{2} }{25}[/tex]
31v² = 625
v² = 20.2
v = 4.5m/s
