A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another
laiz [17]

Answer

given,

watermelon blown into three pieces

two pieces of mass m

both pieces speed = v = 31 m/s

mass of third piece = 3 m

using conservation of mass

0 = m V \hat{i} + m V \hat{j} + (3\ m)V_3

V_3 = \dfrac{V}{3}(-\hat{i}-\hat{j})

V_3 = \dfrac{V}{3}\sqrt{1^2+1^2}

V_3 = \dfrac{V}{3}\sqrt{2}

velocity of third component

V_3 = \dfrac{31}{3}\sqrt{2}

V_3 = 14.61\ m/s

angle

\theta = tan^{-1}(\dfrac{-1}{-1})

\theta = tan^{-1}(1)

\theta = 45^0

Bumek [7]

Answer:

Gravitational force is the force of attraction on a body by earth. Example - Leaves and fruits fall from a tree downwards towards the ground due to the gravitational pull. ... T-shirt for is basically the force Of attraction On a body And this force of attraction on the body is by Earth.

Intermolecular forces act between molecules. ... Intermolecular forces are weaker than intramolecular forces. Examples of intermolecular forces include the London dispersion force, dipole-dipole interaction, ion-dipole interaction, and van der Waals forces.
