Read each question carefully and solve the quantitative problems. Show all your work, including formulas used, substitutions, and final answers with appropriate units.
1. A car accelerates uniformly from rest to 25 m/s in 8.0 seconds. Calculate the acceleration of the car.
2. A ball is dropped from a height of 45 meters. How long does it take to reach the ground? (Assume g = 9.8 m/s²)
3. According to Newton's Second Law, Force = mass × .
4. If a net force of 50 N acts on a 10 kg object, its acceleration will be m/s².
5. Kinetic energy is directly proportional to the square of an object's velocity.
True
False
6. A worker pushes a 20 kg box 5.0 meters across a floor with a constant force of 100 N. Calculate the work done by the worker.
7. If the worker in question 6 completes the task in 2.0 seconds, what is the power output of the worker?
