A) Weight = mass × acceleration (due to gravity)
= 60×9.8
= 588 N
B) Potential energy = mass x gravity x change in height
1,000 = 60.0 x 9.8 x h
h = 1.7 m
C) Kinetic energyF = potential energyI
KEF = 1/2mv2
PEI = mgh = 1,000 J
1/2mv2 = 1,000
1/2(60.0)v2 = 1,000
v2 = 33.33
v = 5.77 m/s
Height of the hill is 1.7 meter (Approx.)
Given that;
Potential energy = 1000 J
Mass = 60 kg
Find:
Height of the hill
Computation:
Potential energy = mgh
1,000 = [60][9.8][h]
h = 1.7 m
Height of the hill = 1.7 meter (Approx.)
