A mysterious crate has shown up at your work . Forecracker company . Amd you are told to measure its inertia. It is too heavy to lift but it rools up smothly on casters .getting an inspiriation you light tape a 0.60kg iron block to the side of the crate , slide a fire cracker between the crate and the block and light the fuse . When the cracker explodes , the block goes in way and thecrate rolls the other way . You measure the crate's speed to be 0.064 m/s by timing how long it takes to cross floor tiles . You look at the specification s of the fire cracker and find that if releases 9J of energy. Thats all you need. And you quickly calculate the inertia of the crate
