Daniel has a sample of pure copper its massive is 89.6 grams(g) and its volume is 10 cubic centimeters (cm3) what's the density of the sample

8.96

Explanation: The formula to find density is the mass divided by the volume

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
