Answer :
Final answer:
The weight lifted by the weightlifter is 145 kg.
Explanation:
The weight lifted by the weightlifter is 145 kg (option 1).
The weight of an object is the force exerted on it due to gravity. In this case, the weightlifter is lifting a mass of 145 kg, and since the acceleration due to gravity is approximately 9.8 m/s^2, the weight can be calculated using the formula:
Weight = mass × acceleration due to gravity
Weight = 145 kg × 9.8 m/s^2 = 1421 N
Therefore, the weight lifted by the weightlifter is 145 kg (option 1).
