Question

Quinn accelerates her skateboard along a straight path from 0 m/s to 4.0 m/s

in 2.5 seconds. Calculate the acceleration of the skateboard

Answer 1

• initial velocity=u=0m/s
• Final velocity=v=4m/s
• Time=t=2.5s

`\\ \sf\longmapsto Acceleration=(v-u)/(t)`

`\\ \sf\longmapsto Acceleration=(4-0)/(2.5)`

`\\ \sf\longmapsto Acceleration=(4)/(2.5)`

`\\ \sf\longmapsto Acceleration=1.6m/s^2`
