Answer:

The distance of a mass 25g from the pivot​ is 18cm

Explanation:

Given

m_1 = 10g

d_1 = 45cm

m_2 = 25g

Required

Distance of m2 from the pivot

To do this, we make use of:

m_1 * d_1 = m_2 * d_2 --- moments of the masses

So, we have:

10 * 45= 25* d_2

450= 25* d_2

Divide both sides by 25

18= d_2

Hence:

d_2 = 18

kherson [118]

Answer:

d=58m

Explanation:

From the question we are told that:

Initial Speed U=12m/s

Time T=5.6s

Angle \theta=30

Generally the  Newton's equation for motion is mathematically given by

d=d'+ut+\frac{at^2}{2}

d=12cos30*5.6

d=58m
