question 4

hi

plz answer this question​

Answer 1

a.

We know,

Average acceleration=(Final velocity-Initial velocity)÷Time=(28-0)/4=28/4=7 m/s^2

b.

We know,

2as=v^2-u^2

=>2×7×s=28^2-0^2

=>14s=784

=>s=784÷14

=>s=56

Therefore,the motorcycle travels 56 metres in 4 seconds.

Answer 2

average acceleration is 28/4=7

distance = speed X time
=28x4
=112
