Question

A body travels 20cm in the first 2sec and 30 cm in the next 4 sec what is the intial velocity​

Answer 1

Answer:

10 cm/s

Explanation:

It travels 20 cm in first 2 seconds

So speed = 20/2 = 10 cm/s

Answer 2

Given :-

• Distance travelled in first 2s = 20cm
• Distance travelled in next 4s = 30cm

To find :-

• Initial velocity = ?

Solution :-

Here the body is travelling 20cm in first 2s . Since it is travelling in first 2s . So it is the initial velocity .

Now , as we know that

• Speed = Distance/Time

=> Speed = 20/2

=> Speed = 10cm/s

Hence, initial speed = 10cm/s
