Given, mass of block 30kg, initital velocity 6.1m/s, final velocity=4.5m/s, change in kinetic energy= mvi^2/2-mvi/2- mvf2/2, KE= 254.4J change in KE= heat generated by friction L=3.4*10^5J/kg, 254.4= m*3.4*10^5, m=0.748gm.

In physics, how do you solve for mass?

There are numerous methods for calculating an object's mass, including:

Mass Equals volume * density (m = V). The mass of an object can be calculated by multiplying its density by its volume because density is a measure of mass per unit of volume. Mass equals force times acceleration (m=F/a). Gravitational acceleration and mass are equal (m=W/g).

What is the center of mass formula?

Center of Mass in a System of Two Particles (m1+m2) rcm equals (m1 r1+m2 r1). The sum of the products of the masses of the two particles and their respective position vectors equals the product of the total mass of the system and the position vector of the center of mass.
