Given:
Ke = 33, 750 joules
v = 30 m/s
Determine the mass of the object.
Formula for Kinetic energy:
Ke = ½ mv^2
2Ke/v^2 = m
Solution:
Substitute the values of Ke and v to the formula for m in terms of V.
m = 2Ke/v^2
m = 2(33,750 joules)/(30m/s)^2
m = 2(33,750 joules)/(30m/s)^2
m = 75 kg
Final answer:
m = 75 kg
