An object’s velocity as a function of time is given by v(t)=bt−ct3, where b and c are positive constants with appropriate units.

A. If the object starts at x=0 at time t=0, find an expression for the time when it’s again at x=0. Express answer in terms of b & c.

B. Find an expression for its acceleration at that time.
Express your answer in terms of variables b and c.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

you can cut your hand off if your not

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
