Q. An alert physics student stands beside the tracks as a train rolls slowly past. He notes that the frequency of the train whistle is 443 Hz when the train is approaching him and 441 -Hz when the train is receding from him. Using these frequencies, he calculates the speed of train. What value does he find? m/s (suppose the speed of sound is 345 m/s.)
A pitcher throws a curveball that reaches the catcher in 0.59 s. The ball curves because it is spinning at an average angular velocity of 380 rev/min on its way to the catcher's mitt. What is the angular displacement of the baseball as it travels ..

A 52.0 kg ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.0 turns each second. The distance from one hand to the other is 1.50 m. Biometric measurements indicate that each hand characterist..
Consider two simple pendulums p and q of equal length l and mass m1 and m2 respectively. assume the bobs of the pendulum are connected to each other by a weightless spring of force constant k such that in the equilibrium position,the spring is uns..
what was the initial speed given to the rock. A light plane is headed due south with the speed of 154 km/h relative to still air. After 1.06 hour, the pilot notices that they have covered only 127km and their direction is not south but southeast (4..
