Ответ:
Centripetal force = 13140 Newton.
Explanation:
Given the following data;
Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg
Velocity = 15m/s
Radius, r = 25m
To find the centripetal force, we would use the following formula:
Centripetal force = mv²/r
Substituting into the equation, we have;
Centripetal force = (1460*15²)/25
Centripetal force = (1460 * 225)/25
Centripetal force = 328500/25
Centripetal force = 13140 Newton.
