The body, with an initial speed of 2 m/s, began to slide along an inclined plane. For l0s, it passes along an inclined plane of 50 m, and then along a horizontal plane to a stop of 90 m. Assuming the body movement in each of the sections to be equally variable, determine the speed of the body at the end of the inclined plane, acceleration on the inclined and horizontal sections of the path, and average speed along the entire path , body movement time.

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
