A boy climbs on to a wall that is 3.4 m high and gains 2250 J of poten...
To find the mass of the boy, we can use the formula for potential energy:
Potential Energy = mass * gravity * height
Given:
Potential Energy = 2250 J
Height = 3.4 m
Gravity = 9.8 m/s^2
Let's substitute these values into the formula and solve for mass:
2250 J = mass * 9.8 m/s^2 * 3.4 m
Simplifying the equation:
mass = 2250 J / (9.8 m/s^2 * 3.4 m)
mass ≈ 67.5 kg
Therefore, the mass of the boy is approximately 67.5 kg.
Answer: Option C (67.5 kg)
Potential Energy = mass * gravity * height
Given:
Potential Energy = 2250 J
Height = 3.4 m
Gravity = 9.8 m/s^2
Let's substitute these values into the formula and solve for mass:
2250 J = mass * 9.8 m/s^2 * 3.4 m
Simplifying the equation:
mass = 2250 J / (9.8 m/s^2 * 3.4 m)
mass ≈ 67.5 kg
Therefore, the mass of the boy is approximately 67.5 kg.
Answer: Option C (67.5 kg)
