A woman lifts a 35-kg child a distance of 1.5 m and carries her forward for 6.5 m.
How much work does the woman do in lifting the child?
Explanation:
Given;
Mass m = 35kg
Distance of lifting l = 1.5m
Acceleration due to gravity g = 9.81 m/s^2
Workdone = mgl = 35×1.5 × 9.81 = 515.025 J
Answer:
So kinetic means to move, something like that right, so the two balls that go in the air are where the kinetic energy is.
Explanation:
Hope it helps.
This one is a piece 'o cake if you know the formula for
Kinetic Energy, and impossible if you don't.
It is: KE = (1/2) (mass) (speed²) .
For this object: KE = (1/2) (30 kg) (20 m/s)²
= (1/2) (30 kg) (400 m²/s²)
= (15 x 400) (kg-m²/s²)
= 6,000 joules .
