You increase your walking speed from 1 m/s to 3 m/s in a period of 1 s.

What is your acceleration?

5 m/s2
3 m/s2
2 m/s2
4 m/s2

Respuesta :

Answer:

2 m/s2

Explanation:

|acceleration| = (change in speed) divided by (time for the change)

Change in speed = (end speed) minus (start speed)

Initial speed of walking = 1 m/s

Final speed of walking = 3 m/s

Change of speed in walking = (3 - 1) m/s

                                            = 2 m/s

Time in which the change of speed occurred = 1 sec

Then

Acceleration = Change of Speed/ Time taken

                    = 2/1 m/s^2

                    = 2 m/s^2

Therefore the answer is 2 m/s2.

The acceleration is 2 m/s².

What is acceleration?

Acceleration can be defined as the rate of change of velocity.

The acceleration can be calculated using the formula below.

Formula:

  • a = (v-u)/t................... Equation 1

Where:

  • a = acceleration
  • v = Final velocity
  • u = Initial velocity
  • t = time.

From the question,

Given:

  • v = 3 m/s
  • u = 1 m/s
  • t = 1 seconds

Substitute these values into equation 1

  • a = (3-1)/1
  • a = 2 m/s².

Hence, The acceleration is 2 m/s².
