Question

a toy dart gun generates a dart with o.140kg.m/s momentum and a velocity of 4m/s. what is the mass of the dart?​

Answer 1

35 kg

Step-by-step explanation:

The momentum of an object is given by:

`p=mv`

where

p is the momentum

m is the mass of the object

v is its velocity

In this problem:

p = 140 kg m/s is the momentum of the dart

v = 4 m/s is its velocity

Solving for v, we find its mass:

`m=(p)/(v)=(140)/(4)=35 kg`
