M a motorboat moving downstream with a velocity 2 m/s with respect to river, a stone is thrown. The stone falls on an ordinary boat at the instant when the motorboat collides with the ordinary boat. The velocity of the ordinary boat with respect to the river is equal to zero. The river flow velocity is given to be 1 m/s. The initial velocity vector of the stone with respect to earth is :- y x Take the value of g = 10 m/s Initial separation between the two boats is 20m. 2?

M a motorboat moving downstream with a velocity 2 m/s with respect to ...
Given data:
- Motorboat velocity downstream: 2 m/s
- Stone falls on ordinary boat when motorboat collides
- Ordinary boat velocity: 0 m/s
- River flow velocity: 1 m/s
- Initial separation between boats: 20m
- Acceleration due to gravity (g): 10 m/s²

Analysis:
- The motorboat's velocity with respect to the river is 2 m/s downstream.
- The river flow adds 1 m/s, so the motorboat's velocity with respect to the Earth is 3 m/s.
- The stone's initial velocity with respect to the Earth is the sum of motorboat's velocity and its velocity with respect to the motorboat.
- Since the ordinary boat's velocity is 0 m/s, the stone's initial velocity with respect to Earth is 3 m/s downstream.
- The stone's horizontal velocity remains constant at 3 m/s, while its vertical velocity changes due to gravity.

Calculation:
- Time taken for motorboat to collide with ordinary boat:
- Initial separation / relative velocity = 20m / 3 m/s = 6.67s
- Vertical distance fallen by stone during this time:
- 0.5 * g * t² = 0.5 * 10 * (6.67)² = 222.67m
- The stone falls on the ordinary boat at this vertical distance and the motorboat collides with it.

Conclusion:
The stone's initial velocity vector with respect to the Earth is 3 m/s downstream in the x-direction. The stone falls on the ordinary boat when the motorboat collides with it after falling a vertical distance of 222.67m due to gravity.

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?
