A70.5kg stunt driver rounds a circular corner at 96.0km/hr (convert to m/s ask if you need ). the centripetal force on the driver is 856n. calculate the radius in meters of the path that the driver took around the circular corner.

= 58.58 m

The centripetal force is given by the formula

Fc = mv²/r ; where m is the mass, v is the velocity and r is the radius of the circular path.

Mass = 70.5 kg. centripetal force = 856 N, and Velocity = 96 km/hr or 26.67 m/s

r = mv²/Fc

 = (70.5 × 26.67²)/ 856 N

  = 58.58 Meters

The radius is 58.27 m

The centripetal force is given by

Fc = mv²/r

By arranging the equation we get

r = mv²/Fc

Putting the values

R = 70.5 * 26.6² / 856    ( 96km/hr is 26.6mp/s)

Radius = 58.27 m

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
