Question

Avika starts from rest and attains a speed of 36 kilometre per hour and 10 minutes calculate the acceleration
pls help fast​

Answer 1

Answer:

0.016 m/s²

Explanation:

Initial velocity is equal to 0 as she starts from rest.

Final velocity is 36 km/hr

But we have to convert this into m/s.

= 36 × 5/18

= 10 m/s

Time = 10 min = 10 × 60 = 600s

Acceleration = v - u / t

= 10 - 0 / 600

= 10 / 600

= 1/60

= 0.016 m/s²

Answer 2

Correct Question:

Avika starts from rest and attains a speed of 36 km/hr in 10 minutes. Calculate the acceleration.

Solution :

• Initial velocity (u) = 0 km/hr

(As she starts from rest)

• Final velocity (v) = 36 km/hr

• Time (t) = 10 min

____________ [ GIVEN ]

We have to calculate the acceleration (a).

______________________________

We know that..

$\star \: { \bold{\boxed{v \: = \: u + \: at}}}$

(Newton's first equation of Motion)

Before putting values, first convert velocity into m/s and time into sec.

Now..

Final velocity (v) = 36 × 5/18

=> 10 m/s

Time (t) = 10 × 60

=> 600 sec

Put them in above formula to find acceleration.

=> 10 = 0 + a(600)

=> 10 = 600a

=> 600a = 10

=> a = 1/60

=> a = 0.0167 m/s²

=> a = 0.017 m/s² (approx.)

______________________________

0.017 m/s² is the acceleration.
