___________ force can be thought of as either a push or a pull, as long as it makes the object move in a circular path.
2 answers:
Explanation:
Centripetal force is a force required by an object to move in a circular path. Mathematically, it is given by :
m is the mass of an object
v is the velocity
r is the radius of circular path
The centripetal force acts towards the center of the circle. The speed of object remains constant while its velocity keeps on changing always. In the absence of the centripetal force, the object moves in straight line.

Maybe the picture helps. The blue block represents the cart with a mass of 3 kg. The person(black block) is pulling the cart to the right with a force F so that the acceleration a is 2 m/s². According to Newton's 2nd law: F = m*a.
Answer:
final displacement lf = 0.39 m
Explanation:
from change in momentum equation:
given: m = 0.4kg, y/x = 19/85, li = 1.9 m,
\delta p = 1.27 kg*m/s.
putting all value to get the final displacement value
final displacement lf = 0.39 m
