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?
1 answer:
Answer:
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

Answer:
Explanation:
I suppose it has to do with the way the diagram is drawn. The heat does not reflect which makes both A and B incorrect.
C would have nothing to do with either reflection or refraction.
That only leaves D which is the answer.
G is the answer for apex vs / Chehhhh
Answer:
distance=speed×time.
45×20=900m.
F = m*a, mass times acceleration.
F = 15*10 = 150 N
Stop using it all the time for some useless things.
