Answer :
Answer:
In this case, the force exerted on the bucket by the rope is 147 N.
Therefore, the correct answer is option a) 147 N.
Explanation:
The force exerted on the bucket by the rope can be determined using Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. In this case, since the bucket is being pulled up at a constant speed, the acceleration is zero.
Therefore, the force exerted on the bucket by the rope is equal to the weight of the bucket. The weight of an object can be calculated using the formula: weight = mass * gravity, where gravity is the acceleration due to gravity (approximately 9.8 m/s² on Earth).
In this case, the mass of the bucket is given as 15 kg. So, the force exerted on the bucket by the rope is:
Force = mass * gravity
= 15 kg * 9.8 m/s²
= 147 N
Therefore, the correct answer is option a) 147 N.
