Explanation:
Given that,
Mass of the cart,
Mass of the cart 2,
Final speed of cart 2,
Final speed of cart 1 is 0 as it comes to rest.
Let us assume that the initial velocity of the cart 2 is 0. So using the conservation of linear momentum as :
So, the initial velocity of the 1.0-kg cart is 0.9 m/s.
Answer:
Fracture or system of fractures in Earth's crust that occurs when stress is applied too quickly or stress is too great; can form as a result of horizontal compression (reverse fault), horizontal shear (strike-slip fault), or horizontal tension (normal fault).
Explanation:
The sum of angles in a regular pentagon is
180*(5 - 2) = 540°
Each internal angle is 540/5 = 108°.
Each vertex creates a line of symmetry to the midpoint of the opposite side,
as shown in the figure.
Answer: 5 lines of symmetry.
To find the answer, take 55 and divide it by 1.85 to get the thickness of one card. In this case the answer would be 29.72973 cm. each.
Answer:
Explanation:
Given that
Mass of disc,M=3 kg
radius r= 65 cm
Mass of small mass ,m=0.07 kg
Initial speed = 2.2 rev/s
If external torque is zero then angular momentum of system will remain conserve.
Moment of inertia of disc at initial condition
Moment of inertia of disc at final condition
So from conservation of angular momentum
This is final speed of disc after small mass flies off from the disc.
