  1. A car starts at 5 m/s and accelerates uniformly at 5 m/s^2 for 6 s. What is its final speed?
  2. An object moves with initial speed 4 m/s and constant acceleration 2 m/s^2. How far does it travel in 5 s?
  3. A 2 kg block is pulled along a rough floor by a horizontal force of 50 N. Friction is 6 N. What is the block's acceleration?
  4. A frictionless slide is 1.25 m high. A child starts from rest at the top. Taking g = 10 m/s^2, what is the child's speed at the bottom?
  5. A car drives around a circular curve of radius 3 m at 6 m/s. What is its centripetal acceleration?
  6. What is the gauge pressure due to water at a depth of 20 m? (density 1000 kg/m^3, g = 10 m/s^2)
  7. An object moves with initial speed 4 m/s and constant acceleration 4 m/s^2. How far does it travel in 3 s?
  8. A ball is thrown straight up at 30 m/s. Taking g = 10 m/s^2 and ignoring air resistance, what maximum height does it reach?
  9. A frictionless slide is 3.2 m high. A child starts from rest at the top. Taking g = 10 m/s^2, what is the child's speed at the bottom?
  10. What is the gauge pressure due to water at a depth of 2 m? (density 1000 kg/m^3, g = 10 m/s^2)
  11. A car starts at 10 m/s and accelerates uniformly at 3 m/s^2 for 4 s. What is its final speed?
