- ***Given Information***
A ball is projected from the ground at an angle θ with the horizontal.
After 1 second, it is moving at an angle 45° with the horizontal.
After 2 seconds, it is moving horizontally.
- ***Analysis***
Let's break down the motion of the ball:
1. **Initial Projection**: When the ball is projected, it has a velocity V at an angle θ with the horizontal.
2. **1 second after projection**: The vertical component of the velocity decreases due to gravity, while the horizontal component remains the same. At this point, the velocity makes an angle of 45° with the horizontal.
3. **2 seconds after projection**: The vertical component of the velocity becomes zero, and the ball is moving horizontally.
- ***Calculations***
1. **Vertical Component of Velocity at 1 second**: V_y = Vsinθ - gt (where g is acceleration due to gravity)
2. **Horizontal Component of Velocity at 1 second**: V_x = Vcosθ
3. **At 1 second, the velocity makes an angle of 45° with the horizontal**: tan(45°) = V_y / V_x
4. **Using the above equations, we can solve for V and θ**.
- ***Final Answer***
By solving the equations, you can find the initial velocity of projection of the ball. This involves using trigonometric functions and kinematic equations to determine the values of V and θ that satisfy the given conditions.
