Question

A cyclist is travelling at 4.0 m/s. She speeds up to 16 m/s in a time of 5.6 s. Calculate her acceleration.​

Answer 1

acceleration: 2.14 m/s²

Step-by-step explanation:

acceleration = (final velocity - initial velocity ) ÷ time taken

Here the final velocity is 16 m/s, initial velocity is 4 m/s, time taken is 5.6 s

acceleration = ( 16 - 4 ) ÷ 5.6

→ 12 ÷ 5.6

→
`\left[\begin{array}{ccc}(15)/(7)\end{array}\right]` m/s² or 2.14 m/s²
