A bat hits a moving baseball. If the bat delivers a net eastward impulse of 1.3 N-s and the ball starts with an initial horizont

Georgia [21]

Answer:

$141.30grams$

Explanation:

First, denote our known values;

$J=1.3N-s(+,east)\\u=-3.8ms^-^1(-,west)\\v=5.4ms^-^1(+,east)\\m=?$

Mass is impulse divided by change in velocity:

$m=\frac{J}{v-u}\\=\frac{1.3}{5.4--3.8}\\\\=\frac{1.3}{9.2}\\=0.1413Kgs$

Hence, the mass of the ball is 141.30grams

Two objects having masses m1 and m2 are connected to each other as shown in the figure and are released from rest. There is no f

tankabanditka [31]

Answer: $m_1g$

Explanation:

Given

Two masses $m_1$ and $m_2$ is released and there is tension T in the string

Suppose a is the acceleration of the system

Therefore from Diagram

For $m_1$

$T-m_1g=m_1a$

$T=m_1(g+a)$ ------1

for m_2 body

$m_2g-T=m_2a$

$T=m_2(g-a)$ -------2

From above two Equation it is said that Tension is greater than m_1g and less than m_2g

$m_1g$
