Question

The effort needed to accelerate objects with a mass of 100 g from 5m / s to 10m / s is

Answer 1

Known :

m = 100 g  

Vo = 5 m / s

Vt = 10 m / s

Asked: Business needed (w)

Settlement:

w = 1/2. m (Vt ^ 2 - Vo ^ 2)

w = 1/2. 100 g (10 ^ 2 - 5 ^ 2)

w = 50 (100 - 25)

w = 50 (75)  

w = 375 J

So, the effort needed is 375 J

Answer 2

Heyy mate ❤✌✌❤

Here's your Answer...

⤵️⤵️⤵️⤵️⤵️

Mass = 100g

Vo = 5m/s

Vt = 10m/s

Now,

W = 1/2 ×100 ×(10^2 - 5^2)

= 50 × ( 100 - 25)

= 50× 75

=3750 Joule.
