What is 15.4mi=1.5hr/v in physics velocity

The velocity is 10.26[mi/hr]

Explanation:

In physics, the velocity is defined as the distance traveled by an object in a time interval.

Now we have:

x = distance = 15.4 [mi]

t = time = 1.5 [hr]

Therefore:

v = x/t

v = 15.4 / 1.5 = 10.26 [mi/hr]

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
