Answer 1

Answer:

Hello dear,

Explanation:

1.Acceleration : acceleration defined as the rate of change of velocity with respect to time. Explanation: its si unit (m/s)^2. formula a=v-u/t.

2.As velocity is attained by aeroplane

     u = 0m/s

     v= 200 m/s

     t = 30 sec

By eq of motion

a =v-u/t

a = 200 -0 /30

a = 200/30

a = 20 /3 = 6.66 m/s^2

3.If the graph forms a straight line with a constant slope, then the motion is uniform, and the slope of the graph is equal to the velocity of the object. If an object exhibits non-uniform motion, a position-time graph of the motion will be curved, not straight. If you graph the velocity of the object.

##the graph is in attachment..

4.Initial velocity = 5m/s

Final velocity = 10m/s

time = 5 sec

Acceleration = ?

We know

➡➡v = u + at

▶▶10=5+a5

▶▶10-5=a5

▶▶5=a5

▶▶5/5=a

▶▶1=a or

▶▶a = 1m/s

hope this answers helps u
