Question

An object O is just about to strike a perfectly reflecting inclined plane of inclination 37∘. Its velocity is 5m/s. Find the velocity of its image.

Answer 1

Thus the velocity of the image is V = ( 4.8 iˆ + 1.4 jˆ )m/s

Explanation:

We are given that:

• Inclined plane inclination of the object = 37∘
• The velocity of the object = 5 m / s

Solution:

Vo = 5m/s

V = 5 cos 37∘ = 9 m / s

V = 5 sin 37∘ = 3 m / s

VI = (5 cos 16∘)iˆ + (5 sin 16∘)jˆ

V = ( 4.8 iˆ + 1.4 jˆ ) m / s

Thus the velocity of the image is V = ( 4.8 iˆ + 1.4 jˆ )m/s
