The 1/2 value comes due to the integration of the Newton's law of motion .. like for doing work we do integrate fds vector. when we integrate it .we get it as 1/2mv^2 + constant
.
Answer:
Change in potential energy = 8.58 J
Explanation:
Potential energy = Mass x Acceleration due to gravity x Height
Potential energy = mgh
m = 2.50 kg
g = 9.81 m/s²
Initial height, h₁ = 1.85 m
Final height, h₂ = 1.50 m
Change in potential energy = mgh₁ - mgh₂
Change in potential energy = 2.5 x 9.81 x 1.85 - 2.5 x 9.81 x 1.50
Change in potential energy = 8.58 J
making cars that get better gas mileage
Answer:
Explanation:
We already know that the wight in reference is <em>gravitational</em> force on an object:.
Gravity=
Weight of car=0.800kg
To solve for A, we apply Newton's second law of radial direction:
Rewrite to calculate acceleration,:
Solving for Position A:
