                                          Kinetic energy = (1/2) (mass) (speed)²

                                         25.2 J                =  (1/2) (5.6kg) (speed)²

Divide each side
by (2.8 kg) :                     25.2 J / 2.8 kg  =                         speed²

Take the square root
of each side:                   speed = √(9 m²/sec²)

                                                      =  3 m/s .

IrinaK [193]
The centripetal force is:
 F = mv² / R
 Where:
 m: mass of the object
 v: object speed
 R: radius of the curve.
 We have to:
 m = 2000kg
 v = 25 m / s
 R = 80 meters.
 Then the centripetal force acting on the vehicle is:
 F = (2000kg * (25m / s) ²) / 80m
 F = 15625 N
