The car’s velocity at the base of the hill is approximately 11.8 m/s.
Solución
Step 1: Determine the Acceleration
The acceleration along the slope of a frictionless incline is given by:
where
Calculating:
Step 2: Use the Kinematic Equation
Since the car starts from rest, the initial velocity
Substituting the given values:
Step 3: Calculate the Final Velocity
First, we compute the product:
Thus:
Taking the square root:

To find the velocity of the car when it reaches the base of the hill, we can use the kinematic equation:
Since the car is rolling down from rest, the initial velocity
Calculating it step-by-step:
So, the velocity of the car as it reaches the base of the hill is approximately
Roller coasters operate on similar principles! They start at a height, converting potential energy to kinetic energy, speeding up as they plunge down inclines. It’s physics in action that creates the thrill of a ride!
Want to calculate the speed of another object rolling down a different slope? Remember to take into account gravitational acceleration and the angle of the incline; just alter the angle or distance to see how physics can vary outcomes!
