Answer:
1. It may change the direction of an object in motion.
2. It may cause change in velocity of an object in motion.
Explanation:
1.It may change the direction of an object in motion.
When an object is in motion,an applied force on that object may change its direction.
For example, a sailboat moving eastward, can suddenly change its direction by interaction of a storm wind blowing form the south.
2. It may cause change in velocity of an object in motion .
A force applied to an object in motion can increase or decrease its speed. When the force is applied to the object in motion in the direction of that object, its velocity may increase.
On the other hand, when the force is applied in the opposite direction to the object in motion, its velocity may reduce.
The required initial velocity that will result if a projectile lands at the same height from which it was launched is V₀ = V cosθ
First, we must understand that the component of the velocity along the vertical is due to maximum height achieved and expressed as usin
θ.
The component of the velocity along the horizontal is due to the range of the object and is expressed as ucosθ.
If the <u>air resistance is ignored</u>, the velocity of the object will be constant throughout the flight and the initial velocity will be equal to the final velocity.
Hence the required initial velocity that will result if a projectile lands at the same height from which it was launched is V₀ = V cosθ
