Solution: A 15 kg object moves along a path given by x(t) = 3m - (1.7 m/s)t + (0.7 m/s3)t3. (a) What is the object's momentum as a function of time?(b) What is the force (as a function of time) acting on the object?

Problem

A 15 kg object moves along a path given by x(t) = 3m - (1.7 m/s)t + (0.7 m/s3)t3

(a) What is the object's momentum as a function of time?

(b) What is the force (as a function of time) acting on the object?
