Challenge Problems

Push your limits with challenges.

Question 1

A car moving in the negative direction increases its velocity while the acceleration is negative. Explain what this implies in terms of motion.

💡 Hint: Think about what happens to speed when you apply brakes in a car.

Question 2

A projectile is thrown upwards with a positive velocity but has a negative acceleration. Calculate its peak height given the initial velocity of 20 m/s and acceleration of -9.8 m/s².

💡 Hint: Remember the kinematic equation for uniformly accelerated motion.
