Question

A motorcycle moving with velocity and 30m/s accelerate with 4m/s2 to gain velocity of 6mls. calculate its time to gain that velocity​

Answer 1

• Initial velocity=30m/s=u
• Acceleration=a=4m/s^2
• Final velocity=v=6m/s
• Time=t

Using first equation of kinematics

`\boxed{\sf v=u+at}`

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

`\\ \sf\longmapsto t=(30-6)/(4)`

`\\ \sf\longmapsto t=(24)/(4)`

`\\ \sf\longmapsto t=6s`
