A car of mass 1270 kg makes a 15.0 m radius turn at 11.8 m/s on flat ground. How much centripetal force acts on it? (Unit = N)

Please help. Every answer that I try doesn't work!!

11789 N

Explanation:

The following data were obtained from the question:

Mass (m) = 1270 kg

Radius (r) = 15 m

Velocity (v) = 11.8 m/s

Centripetal force (F) =?

The centripetal force that acted on the car can be obtained by using the following formula:

F = mv²/r

Where:

F is the centripetal force.

m is the mass.

v is the velocity.

r is the radius.

Thus, with the above formula, we can obtain the centripetal force as follow:

Mass (m) = 1270 kg

Radius (r) = 15 m

Velocity (v) = 11.8 m/s

Centripetal force (F) =?

F = mv²/r

F = 1270 × 11.8² / 15

F = 1270 × 139.24 / 15

F = 176834.8 / 15

F = 11789 N

Therefore, the centripetal force that acted on the car is 11789 N

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

so easy. just google the electromagnetic waves and it’ll pop up.
