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

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
