I know half on number one it is repulsive
Explanation:
Answer:
d. may be either greater, smaller, or equal to that observed inside the bus.
Explanation:
- The bus is moving at a constant speed. The ball tossed and received by the ball is inside the bus at a speed equal to the speed of the ball. Therefore the speed of the bus becomes zero with respect to the observer inside the bus.
- Now the observer inside the bus noticed the ball from the inside of the bus, so he threw the ball back and forth from the ball with the speed v relative to the observer.
- Now the observer outside the bus could see the bus moving at speed relative to its reference point and also throwing the ball from front to back. The speed of the ball to the observer outside the bus The speed of the bus to the observer outside the bus is minus the speed of the ball to the observer inside the bus.
- Therefore, the ball speed = (u-v) relative to the observer outside the bus.
Answer:
Explanation:
Given
