1. A car accelerates uniformly from rest to a speed of 20 m/s in 5 seconds. Calculate the car's acceleration and the distance it travels during this time.\n 2. Calculate the gravitational potential energy of a 2 kg object raised to a height of 10 meters above the ground. Take gravitational acceleration as 9.8 m/s².\n 3. A 5 kg object is moving at a velocity of 10 m/s. Find its kinetic energy.\n 4. If a force of 15 N is applied to an object and it moves 4 meters in the direction of the force, calculate the work done.\n 5. A pendulum completes one full swing in 2 seconds. Determine its frequency and period.\n These questions cover basic principles of motion, energy, force, and simple harmonic motion relevant for senior high school physics.
