Answer:
Velocity is a vector quantity. It has both, magnitude and direction. Velocity is the rate of change in the position of a body with respect to a frame of reference. One component is the magnitude of velocity which is speed. The other one is its direction.
Explanation:
Speed is a scalar quantity.
Velocity is a vector quantity.
There are two types of quantities:
1. Scalar quantity:
A scalar quantity is a quantity which is described by its magnitude alone.
2. Vector Quantity:
A vector quantity is a quantity which is described completely by both, its magnitude and direction.
Answer:
Velocity of ball1 after the collision is 0.35 m/s at 53.87° due south of east.
Explanation:
By conservation of the linear momentum:
Since both masses are the same, and expressing the equation for each axis x,y:
eqX
eqY
From eqX:
From eqY:
The module is:
The angle is:
This is 53.87° due south of east
The answer is B
