Question

4th question with step

Answer 1

Answer:

Initial velocity(u) =10m/s

Initial velocity(u) =10m/sFinal velocity(v) =60m/s

Initial velocity(u) =10m/sFinal velocity(v) =60m/sAcceleration =(v-u)/t

Initial velocity(u) =10m/sFinal velocity(v) =60m/sAcceleration =(v-u)/t a=(60-10)/10

Initial velocity(u) =10m/sFinal velocity(v) =60m/sAcceleration =(v-u)/t a=(60-10)/10 a=50/10

a=50/10 a=5

Therefore, acceleration is 5m/s.

Mark it as brainliest plz if it helps you. Best of luck

Answer 2

Answer:

acceleration=final velocity- initial velocity÷time

acc. =60-10÷10

acc. =50÷10

acc.=5m per second square

hope this answer will help you
