Given Ma050 Kg Use The Graph To Calculate The Mass Of Cart B Explicitly Indicate The Principles Used In Your Calculations class=

Sagot :

The mass of Cart B in the cart system is : 1 kg

Given data :

mass of cart A = 0.5 kg

Making Use of  the graph attached below

Principle of energy conservation

we will apply the principle of energy conservation of momentum

velocity of cart A ( from 0s to 1s ) = 1.5 m/s

mass of cart A = 0.5 kg

at this point cart B is at rest

Initial momentum = 0.75 kgms ( mass * velocity )

From ( 1.2secs to 2 secs ) :

combined Velocity of Cart A and Cart B = 0.5 m/s

momentum = 0.75 kgms

Therefore combined mass of cart system

= momentum / velocity

= 0.75 / 0.5

= 1.5 kg

Therefore mass of Cart B = combined mass - mass of cart A

                                           = 1.5 - 0.5 = 1 kg

Hence we can conclude that the mass of cart B is = 1 kg
