Hi there!
Recall the following relationships:
W = Work (J)
U = Potential Energy (J)
m = mass (kg)
g = acceleration due to gravity (9.8 m/s²)
h = height (m)
t = time (s)
Begin by calculating the work:
Now, divide by the time to solve for power:
**W is the unit for power (Watts). Be careful not to get the two confused.
Answer:
Acceleration of Object A = 0.6 m/s²
Acceleration of Object B = 0.3 m/s²
Acceleration of Object A is double than the acceleration of Object B.
Explanation:
According to the Newton's 2nd law of motion, Acceleration of an object by a net force is directly proportional to the magnitude of that net force and in the direction of that net force and inversely proportional to the mass of the object
Mathematically
F ∝ a
F = ma
Given data:
F = 15 N
m₁ = 25 kg
m₂ = 50 kg
F = m₁a₁
a₁ = F/m₁
a₁ = 15/25
a₁ = 0.6 m/s²
F = m₂a₂
a₂ = F/m₂
a₂ = 15/50
a₂ = 0.3 m/s²
It can be seen that acceleration of Object A is double than the acceleration of Object B.
