Question

Abus increases its speed from 36 km/h to 72 km/h is
10 seconds Its accelestion is​

Answer 1

Answer:

Initial Velocity = 36 km/hr

= 10 m/s

Final Velocity = 72 km/hr

= 20 m/s

Time = 10 sec

Acceleration = ∆V/∆t

$= \frac{20 - 10}{10} \\ = \frac{10}{10 } \\ = 1 {m} {s}^{ - 2}$

Answer 2

Answer:

Acceleration: 1 m/s^2

Explanation:

Given:

Initial speed v1: 36km/h =10m/s

finial speed v2: 72 km/h = 20m/s

time t= 10sec

To find:

Acceleration a=?

Formula: v2-v1÷t (final speed v2 subtracted by initial speed v1 and divided by time t)

Solution:

v2-v1÷t

putting given values,

20m/s-10m/s÷ 10s

we get, 1 m/s^2
