Answer :
The velocity when it hits the ground is 10i + 6.26j m/s
Calculation
Let us take horizontal is x-axis and vertical is Y-axis
Uy= 0
Sy= 2m
a= 9.8m/[tex]s^{2}[/tex]
t=[tex]\sqrt{\frac{2Sy}{a} }[/tex] = 0.639
Vy= 9.8x0.639
=6.26
Thus, velocity in vector form is 10i + 6.26j m/s.
Concept of velocity
Velocity is the pace and direction of an object’s movement, whereas speed is the time rate at which an object is travelling along a path.
What is velocity, for instance?
Velocity can be defined as the rate at which something moves in a specific direction.
As the speed of a car driving north on a highway or the pace at which a rocket takes off. The scalar refers to the magnitude.
