Questions & Step-by-Step Solutions
A cyclist accelerates from rest to a speed of 10 m/s in 5 seconds. What is the acceleration? (2023)
Step 1: Identify the initial velocity of the cyclist. Since the cyclist starts from rest, the initial velocity is 0 m/s.
Step 2: Identify the final velocity of the cyclist. The final velocity is given as 10 m/s.
Step 3: Identify the time taken for the acceleration. The time is given as 5 seconds.
Step 4: Use the formula for acceleration: Acceleration = (final velocity - initial velocity) / time.
Step 5: Substitute the values into the formula: Acceleration = (10 m/s - 0 m/s) / 5 s.
Step 6: Calculate the result: Acceleration = 10 m/s / 5 s = 2 m/s².
Acceleration – Acceleration is the rate of change of velocity over time, calculated as the difference between final and initial velocity divided by the time taken.
Kinematics – Kinematics is the branch of mechanics that deals with the motion of objects without considering the forces that cause the motion.
