Question 1
What is the formula for average velocity?
- Δv = Δx / Δt
- Δv = Δt / Δx
- Δv = x_f + x_i
💡 Hint: Recall how we define average velocity.
Question 2
Is kinetic energy dependent on mass and velocity? True or False?

Question 1
A 60 kg skier starts from rest and descends a slope, reaching a speed of 15 m/s. Calculate the work done by gravity, assuming a height loss of 30 m.
💡 Hint: Consider the gravitational potential energy change.
Question 2
Two ice skaters collide on a frictionless surface – Skater A with mass 50 kg moving at 4 m/s and Skater B with mass 75 kg moving in the opposite direction. Calculate the final velocity of the skaters if they cling together after the collision.
💡 Hint: The initial momentum before the collision should equal the momentum after.
