Bob proposed Alice to a marriage on the very top of a 30m building. Alice said yes. Bob then put the ring on Alice’s finger. Alice was very happy. She threw her hands up in the air. Unfortunately, the ring slipped from her finger and fell down due to gravity. Bob set up a camera to record the moment. Thus, he look at the footage and determine that the ring was going out of Alice’s hand with speed of vi =10m/s at an angle of θ=30 . The dimension of the building is given below. (a) If the ring were to land on the terrace, how long would it take? (b) If the ring were to land on the Lawn, how long would it take? (c) Where should Bob search for the ring? Terrace or lawn?

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.
