Explanation:
The area between the speed-time graph f a body and time axis measures the distance travelled by the body
Answer:
Average Velocity = 3.65 m/s
Explanation:
Average Velocity
Basically, we want to see the distance in terms of thickness. So, for this rectilinear motion at constant acceleration, the equation to be used is:
x = v₀t + 0.5at²
First, let's determine t using the equation:
a = |v - v₀|/t
300 m/s² = |0 - 92.8 km/h * 1,000 m/1 km * 1 h/3600 s|/t
t = 0.086 seconds
x = (92.8 km/h * 1,000 m/1 km * 1 h/3600 s)(0.086 s) + 0.5(300 m/s²)(0.086 s)²
x = 3.33 meters
Weight of the 120kg mass object on the moon
It is a fact that the gravity on the Moon is (1/6)th that on the Earth.
Assuming g ≈ 10 m/s² on the earth.
W = m*(g moon) = 120 * (10/6) = 200N.
Weight on moon = 200N.
The object would weigh approximately 200N on the moon.. The force of gravity acting on the object on the moon is the same as the weight of the object on the moon.
