1. Gunter, the weightlifter, can lift a 230.0 kg barbell overhead on Earth. The acceleration due to gravity on the sun is 274 m/s2.
2. a. Would the barbells be heavier on the sun or on the Earth.
heavier on the sun
b. How much (in Newtons) would the barbells weigh on the sun?
63020 N
2a. correct
2b. correct, assuming the weights didn't melt before the lift.
To calculate the weight of the barbells on the sun, we can use the formula:
Weight = mass x acceleration due to gravity
Given that Gunter can lift a 230.0 kg barbell on Earth, we can convert the weight to Newtons using the following equation:
Weight on Earth = mass x acceleration due to gravity on Earth
Weight on Earth = 230.0 kg x 9.8 m/s^2 (approximate value for acceleration due to gravity on Earth)
Weight on Earth ≈ 2,254 N
Since we know that the acceleration due to gravity on the sun is 274 m/s^2, we can use the same formula to find the weight of the barbells on the sun:
Weight on the Sun = mass x acceleration due to gravity on the sun
Weight on the Sun = 230.0 kg x 274 m/s^2
Weight on the Sun ≈ 63,020 N
Therefore, the barbells would be heavier on the sun and would weigh approximately 63,020 Newtons.
To determine if the barbells would be heavier on the sun or on Earth, we need to compare the weight of the barbells on both bodies. Weight is the force exerted on an object due to gravity.
1. On Earth:
The weight of an object on Earth can be calculated using the equation:
Weight = mass * acceleration due to gravity on Earth (9.8 m/s^2).
Given that Gunter can lift a 230.0 kg barbell overhead on Earth, we can calculate the weight on Earth as:
Weight on Earth = 230.0 kg * 9.8 m/s^2 = 2254 N.
2a. On the Sun:
To determine if the barbells would be heavier on the sun, we need to compare the acceleration due to gravity on the sun with that on Earth. Given that the acceleration due to gravity on the sun is 274 m/s^2, which is significantly higher than 9.8 m/s^2 on Earth, we can infer that the barbells would be heavier on the sun.
2b. To calculate the weight of the barbells on the sun, we can use the same equation as before:
Weight on the Sun = mass * acceleration due to gravity on the sun (274 m/s^2).
Using the mass given as 230.0 kg, we can calculate the weight on the sun as:
Weight on the Sun = 230.0 kg * 274 m/s^2 = 63,020 N.
Therefore, the barbells would be heavier on the sun, with a weight of 63,020 Newtons.
