A960 kg car initially moving at 30.0 m/s hits a 150-kg deer initially running at 12.0 m/s in the same direction. after the hitting. the deer remains on the car. what is the final velocity (in m/s)?

V = 27.56 m/s

Explanation:

It is given that,

Mass of the car,

Initial speed of the car,

Mass of the deer,    

Initial speed of the deer,

It is mentioned that after the hitting. the deer remains on the car. It is a case of inelastic collision. Let V is the speed of final speed of the deer and the car. Using the conservation of momentum to find it as :

V = 27.56 m/s

So, the final velocity of the deer and the car is 27.56 m/s.

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.

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

any of the answers are correct.
