Acar moving at 10.0 m/s encounters a bump that has a circular cross-section with a radius of 30.0 m. what is the normal force exerted by the seat of the car on a 60.0-kg passenger when the car is at the top of the bump?
a) 200 n
b) 389 n
c) 789 n
d) 589 n

force at the top will be 388 N which is nearly equal to 389

option (b) is correct

Explanation:

We have given velocity of the moving car v = 10 m/sec

Radius of the circular section r = 30 m

Mass of the passenger m = 60 kg

Acceleration due to gravity

At the top normal force is given by

So force at top will be

So force at the top will be 388 N which is nearly equal to 389

So option (b) is correct

option B

Explanation:

given.

car is moving at = 10 m/s

bump of radius = 30 m

normal force = ?

mass of the passenger = 60 kg

m × g = 60 × 9.81 N

normal force acting

                 =

                 =

                 =388.6 N

the normal force acting is equal to 389 N

hence, the correct answer is option B

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
