Question

What is the velocity of an object that has a momentum of 4,000 kg-m/s and a mass of 115 kg? Round to the nearest hundredth.

A. 34.78 m/s
B. 36.5 m/s
C. 37.43 m/s
D. 35.67 m/s

Answer 1

Answer: A.

Explanation:

V = M (kg*m/sec) /m (kg) = 4000/115 = 800/23 = 34.7826.. m/sec

Answer 2

Answer: 34.78 m/s

Step-by-step explanation:

The momentum
`p` is given by the following equation:

`p=m.V` (1)

Where:

`m` is the mass of the object

`V` is the velocity of the object

Finding the velocity from (1):

`V=(p)/(m)` (2)

`V=(4000kg.m/s)/(115kg)`

Finally:

`V=34.78m/s` >>>This is the velocity of the object
