### Question

A car moving with a velocity of 20m/s at 30° to the horizontal, what is the component of the velocity along the horizontal?

A) 17.3m/s

B) 10m/s

C) 20m/s

D) 21m/s

E) 34m/s

• 20 cos30 =17.3m/s

• Praise Odulesi

Velocity= 20m/s

Angle=30°

Velocity component along horizontal= UCosTita

= 20Cos30

Cos 30= 0.8660
:. 20 × 0.8660

=17.32
~ 17.3m/s

Option A
