The initial velocity of a ball in 2D projectile motion can be calculated using the formula v = √(gx^2 + 2gh), where g is the acceleration due to gravity, x is the horizontal distance, and h is the vertical distance.
The trajectory of a ball in 2D projectile motion can be described by the equation y = xtanθ - (gx^2 / 2v^2cos^2θ), where y is the vertical displacement, x is the horizontal displacement, θ is the launch angle, and v is the initial velocity.
The angle of the inclined plane affects the motion of the ball by changing the acceleration due to gravity. As the angle increases, the vertical component of gravity decreases, causing the ball to accelerate less and travel a shorter distance on the inclined plane.
The time of flight for a ball in 2D projectile motion can be calculated using the formula t = (2v sinθ)/g, where v is the initial velocity and θ is the launch angle.
Yes, the initial velocity of the ball can be changed to make it reach a specific point on the inclined plane. This can be done by adjusting the launch angle and initial speed of the ball, using the equations mentioned above, to achieve the desired trajectory and landing point on the inclined plane.
