A505-n rightward force is use to drag a large box across the floor with a constant velocity of 0.62 m/s. the coefficient of friction between the box and the floor is 0.7. determine the mass of the box.

73.62 kg

Explanation:

Given;

Also

where m is the mass of the box,

g is acceleration due to gravity = 9.8 m/s²

is coefficient of friction = 0.7

-505 = - (m*0.7*9.8)

-505 = -6.86 m

m = 505/6.86

m = 73.62 kg

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
