Question

A force of 10kg wt acting on a certain mass for 2 second gave it a velocity 10 m/s. what is mass in kg? ( g = 9.8 m/s^2)​

Answer 1

Answer:

19.6 kg

Explanation:

Given :

To find the value of mass in kg if, a force of 10kg weight acts on a certain mass for 2 second gave it a velocity of 10 m/s.

(given g = 9.8 m/s²)

Solution :

We know that,

$F = m_1a_1 = m_2(\frac{v - u}{t} )$

$m_1$ = 10 kg (given)

a = g = 9.8 m/s² (given)

v = 10 m/s (given)

u = 0 m/s (given)

t = 2 seconds (given)

_

$m_1a_1 = m_2(\frac{v - u}{t} )$

⇒ $10 \times 9.8 = m_2 \times \frac{10 - 0}{2}$

⇒ $98 = 5 m_2$

⇒ $m_2 = \frac{98}{5} = 19.6$ kg

Answer 2

Answer:

here is your answer

M1 A1 =M2 [v-4 / t]

10×9.8 =M2=98/5 = 19.6 kg

so, the answer is 19.6 kg
