Answer 1

Answer:

Hope it helps you......(✿◕‿◕✿)

Explanation:

➧ Given:-

▪ Initial velocity of object (u) =20m/s

▪Final velocity of object (v) =50m/s

▪Time taken (t) =10 second

➧ To Find:-

Acceleration of object????

➧Solution :-

➠ By using first equation of motion

v = u + at

50 = 20 + a x 10

a = (50 - 20) / 10

a = 30 / 10

a = 3 m/s²

∴ The required answer is 3m/s² .

Answer 2

Given

initial velocity (u) = 20 m/s

final velocity (v) = 50 m/s

time = 10sec.

AS WE KNOW

ACCELERATION=Final velocity-initial velocity/time

SOLUTION

a = v-u/t

= 50 m/s-20 m/s /10sec

= 30m/s / 10sec

= 3 m/sec^2

SO THE ACCELERATION IS 3 m/sec^2
