A person sitting in the rear end of a compartment throwsa ball towards...

Explanation:

To solve this problem, we need to apply the concept of projectile motion. The ball is thrown with an initial velocity in the forward direction, while the train is moving with a uniform velocity in the same direction. As a result, the ball follows a parabolic path with respect to both the thrower and the outside observer.

Maximum height attained (hm):

The maximum height attained by the ball depends on the initial velocity and the angle of projection. Since the initial velocity is the same for both the thrower and the outside observer, the maximum height attained by the ball will be the same for both of them.

Range seen (R):

The range of the ball depends on the initial velocity and the angle of projection, as well as the time of flight. The time of flight, in turn, depends on the vertical velocity component and the acceleration due to gravity. Since the vertical velocity component and the acceleration due to gravity are the same for both the thrower and the outside observer, the time of flight and thus the range seen by both of them will be the same.

Therefore, the correct option is A, i.e., the maximum heights attained by the thrower and the outside observer will be the same, but the ranges seen by them will be different. This is because the observer on the ground sees the ball moving forward with respect to the ground, while the thrower sees the ball moving forward with respect to the train. As a result, the observer on the ground sees the ball covering a greater horizontal distance than the thrower, and thus the range seen by the outside observer is greater than that seen by the thrower.

Basketball and projectileUsing the laws of physics, it is possible to make a successful jump shot in basketball every time. The trajectory of a basketball is always is a parabola when it is launched up into the air, and this is due to the affects of gravity as well as the force put on the ball by the player and its property follows the properties of a projectile.The ball's velocity changes as it moves through the air, but the velocity of the first half of the path matches with the last half of the path. It may deviate from its path if the ball collides with either the backboard or another player interfering with its path. From the information of the height of the player, the horizontal distance and height of the hoop, the player can easily calculate the speed to be imparted to the ball and the angle for a sure success. If player’s height is 1.27 meters standing at a distance of 2 meters from the hoop which is at an height of 3.05 meters, he needs an angle of 55° and velocity of the ball 7 m/s to be imparted to make his shot a success. (If he uses a smaller angle has to shoot with a greater velocity.) If he stands 6 meters distance from the hoop, he needs an angle 60° and a velocity 9.5 m/s to be successful. To improve chances of an accurate shot, often a player includes a backspin on the ball as he launches it for a shot. The backspin ensures that the ball enters the hoop, especially if the shot is a "soft shot." Soft shot is when the ball is shot at a low angle and low velocity, the player adds a backspin because if the ball winds up hitting the rim, the spin will help it to enter the hoop. The backspin changes the velocity direction (once it hits the rim) to the opposite direction of the rim rather than bouncing it out.When the basketball deviates from its parabolic path?
