Answer:
Horizontal component of velocity =1.7364m/s
Vertical component of velocity =9.848m/s
Explanation:
As the ball is a 2D projectile,it has two components.
Concept of components of a vector:
1)All the possible independent components of a vector sum up to give the vector.
2)If the magnitude of a vector is v,then its component in the direction at an angle of Θ from the vector is equal to - vcos(Θ).
Now as the ball is having 2D motion,it has two independent components one along the horizontal,one along the vertical.
Given angle of velocity with horizontal =°
Therefore angle of velocity with vertical °°
°
Therefore,
Component of Velocity along horizontal =
cos(80°)
Component of velocity along vertical =
cos(10°)
Therefore
Horizontal component of velocity of ball =1.7364m/s
Vertical component of velocity of ball =9.848m/s
