Arace car rounds a curve at 59 m/s. the radius of the curve is 440 m, and the car's mass is 615 kg. (assume the car's speed remains constant. take the radially inward direction to be positive. indicate the direction with the sign of your answer.) (a) what is the car's (centripetal) acceleration? m/s2 what is it in g's? g (b) what is the centripetal force acting on the car? n

Part a)

Part b)

Explanation:

Part a)

As we know that centripetal acceleration is given as

here we know that

now we will have

Part b)

Centripetal force is given as

are there answer choices to this question? this seems like a question where you have options to choose from.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
