Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the formula for calculating final velocity with constant acceleration?

💡 Hint: Think about initial velocity and the effect of acceleration over time.

Question 2

Easy

If a bicycle starts at 10 m/s and accelerates at 2 m/s² for 4 seconds, what is its final speed?

💡 Hint: Use v = u + at.

Question 1

What is the equation for final velocity given initial velocity, acceleration, and time?

  • v = u + at
  • s = ut + ½ at²
  • v² = u² + 2as

💡 Hint: Look for the equation that directly includes time.

Question 2

True or false: The equation s = ut + ½ at² can be used when acceleration is constant.

  • True
  • False

💡 Hint: Recall when we discussed this equation.

Challenge Problems

Push your limits with challenges.

Question 1

A train traveling at a speed of 25 m/s starts from rest and uniformly accelerates to 75 m/s. Calculate the distance it traveled while accelerating.

💡 Hint: First, determine acceleration using the time taken or another relevant fact.

Question 2

A stone is thrown vertically upward with an initial velocity of 20 m/s. Calculate the maximum height it reaches, considering gravity is -9.8 m/s².

💡 Hint: Remember that at peak height, the vertical speed will be zero.
