Answer:
They have each lost the same amount of potential energy. (The lost potential energy is converted to kinetic energy.)
Answer:
3600N
Explanation:
Given: m = 1200kg, Vo = 0m/s, Vf = 30m/s, Δt = 10s
ΣF = ma
we need to find 'a' first, using the definition of 'a' we get equation:
a = (Vf-Vo)/Δt
a = (30m/s)/10s
a = 3 m/s^2
now substitute into top equation
ΣF = ma
Fengine = (1200kg)(3m/s^2)
Fengine = 3600N
Answer:
488 = r
Explanation:
362 = -126 + r; 488 = r

A variable (often denoted by y ) whose value depends on that of another.
No it isn't. It's called an electrostatic field or an electric field.
