Q1. A horse canters away from its trainer in a straight line, moving 120 away in 15.1. It then turns abruptly and gallops halfway back in 5.0
Q2. A golf ball is struck with a five iron on level ground. It lands 92.7 away 4.10 later. What were (a) direction and (b) magnitude of the initial velocity?
Q3. Water in an electric teakettle is boiling. The power absorbed by the water is 1.00 kW. Assuming the pressure of vapor in the kettle equals atmospheric pressure; find out the speed of effusion of vapor from the kettle's spout if the spout has a cross-sectional area of 2.00 cm2. Model steam as an ideal gas.
