Question

a bus starts to move from rest if its velocity becomes 90 km per hour after 8 s calcule its accelration with full process

Answer 1

Answer:

the answer will be 11250 m/s^2

Step-by-step explanation:

u= initial velocity

v= final velocity

acceleration formula= v-u/time

after changing units =

90000- rest(0)/8secs

Answer 2

QUESTION:-

a bus starts to move from rest if its velocity becomes 90 km per hour after 8 s calcule its accelration .

EXPLANATION:-

• Initial velocity(u)=0 m/s
• Final velocity=90 km/hr=90×5/18=>25 m/s
• Time(t)=8 s
• Acceleration(a)=??

Let's apply 1st equation

→v=u+at

→25=0+a8

→a=25/8

→a=3.125 m/s²
