The X component of the vector is 11.5 while the Y component is 9.6.

<h3>What are the components of a vector?</h3>

We know that a vector must posses both magnitude and direction. Now the vector could be resolved into the vertical and the horizontal components of the mixture.

In resolving this vector;

X component = 15 cm cos 40 degrees = 11.5

Y component = 15 cm sin 40 degrees = 9.6

Thus the X component of the vector is 11.5 while the Y component is 9.6.

vodka [1.7K]

Answer:

51.96 m/s^-1

Explanation:

a) see the attachment

b) As we know the velocity of the projectile has two component, horizontal velocity v_ox. and vertical velocity v_oy as shown in the figure. At the highest point of the trajectory, the projectile has only horizontal velocity and vertical velocity is zero. Therefore at the highest point of the trajectory, the velocity of the projectile will be

v_ox=v_o*cosФ

=60*cos (30)

= 51.96 m/s^-1
