A bicycle racer rides around a circular track of radius R. The racer speeds around its first lap at linear speed 1
v;. Later, their speed decreases to Vi.
3
How does the magnitude of the racer's centripetal acceleration change after the linear speed decreases?

Suppose that three astronomical objects, 1, 2, and 3 are observed to lie on a line, and the distance from object 1 to object 3 is d. object 1 has four times the mass of object 3, and seven times the mass of object 2. find the distance between objects 1 and 2 for which the net force on object 2 is zero.
