Two grocery carts collide, a full one with a mass of 35 kg moving East at 2 m/s and an empty one with a mass of 10 kg moving West at 3 m/s. After the collision the full cart is moving East at 0.75 m/s. What is the velocity of the empty cart?

HEYA!!!


HERE IS YOUR ANSWER,

>> GIVEN : 
Mass (m₁) = 35 Kg. Mass (m₂) = 10 Kg, Initial Velocity (u₁) = 2 m/s, Initial Velocity (u₂) = -3 m/s and Final Velocity (v₁) = 0.75 m/s and Final Velocity (v₂) = ? 

>> SOLUTION :

Applying Law Of Conservation of Momentum, 

→ m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

→ (35 × 2) + (10 × -3) = (35 × 0.75) + 10v₂ 

→ v₂ = (70 - 30 - 26.3) ÷ 10

→ v₂ = 1.4 m/s (EAST)

>> THEREFORE,

Final velocity (v₂) = 1.4 m/s (EAST)


HOPE IT HELPS YOU,
THANK YOU.

Solution:-
given ,
m1 = 35kg, u1=2m/s , m2= 10kg
u2 = -3m/s (opposit east side) , v1= 0.75m/s , v2= ?

by law of conservation of momentum

= m1u1+m2u2 = m1v1+m2v2

= 35×2+10×(-3 )= 35×0.75 +10v2

= 10v2 = 70-30-26.25

= v2 = 13.75/10 = 1.35 by round figure

= v2 = 1.4m/s (east) ans
