Acertain light truck can go around a flat curve having a radius of 150 m with a maximum spee dof 32.0 m/s. with what maximum speed can it go around a curve having a radius of 75.0 m?

Answer

Maximum speed at 75 m radius will be 22.625 m /sec

Explanation:              

We have given radius of the curve r = 150 m

Maximum speed

Coefficient of friction

Now new radius r = 75 m

So maximum speed at new radius

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.
