Weight = (mass) x (acceleration of gravity at the place where the mass is) .
Man's mass = 80 kg
His weight on Earth = (80 kg) x (9.8 m/s²) = 784 newtons (about 176 pounds)
His weight on the Moon = (80 kg) x (1.63 m/s²) = <em>130.4 newtons</em> (about 29.2 pounds)
His mass is <em>80 kg</em>. Mass is the thing about him that doesn't change.
He has the same mass on the Earth, on the Moon, or anywhere.
Answer:Like friction, the drag force always opposes the motion of an object. ... The drag coefficient can depend upon velocity, but we will assume that it is a ... At highway speeds, over 50% of the power of a car is used to overcome air drag. ... A zero net force means that there is no acceleration, as given by Newton's second law.
Answer:
The equations are :
h = 18 + 1.5t
h = 5 + 24t - 16t^2
Explanation:
Speed = distance/time
1.5ft/s = 18ft/t
1.5t=18
The equation to determine height h= 18 + 1.5t
Graham moved another 5ft further with a velocity of 24ft/s
The equation to determine his height will be:
h= 5 + 24t -16t^2
