Final answer:
The force required to push the 25 kg object up the 30-degree ramp is 220 N.
Step-by-step explanation:
In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction. To calculate the force required to push the object up the ramp.
we need to consider the component of the weight of the object that acts parallel to the ramp. This component can be calculated using the formula: Force = Weight * sin(angle). Using this formula, and given that the weight of the object is 25 kg multiplied by the acceleration due to gravity (9.8 m/s²), we can calculate the force as: Force = 25 kg * 9.8 m/s² * sin(30°)
Simplifying this expression gives us the force required to push the object up the ramp. Therefore, the answer is Option 3: 220 N.
