Concept explainers
A motorcycle racer travelling at 145 km/h loses control in a corner of the track and slides across the concrete surface. The combined mass of the rider and bike is 243 kg. The steel of the motorcycle rubs against the concrete road surface. (a) What is the frictional force between the road and the motorcycle and rider? (b) What would be the acceleration of the motorcycle and rider during the wipeout? (c) Assuming there were no barriers to stop the motorcycle and rider, how long would it take the bike and the rider to slow to a stop?

- please help me solve all parts of this question from physics. thanks so much in advance! :)))arrow_forwardA fluid with density 263 kg/m3 flows through a pipe of varying diameter and height. At location 1 the flow speed is 13.5 m/s and the diameter of the pipe is 7.4 cm down to location 2 the pipe diameter is 16.9 cm. Location 1 is 6.3 meters higher than location 2. What is the difference in pressure P2 - P1? Using units in Pascals and use g = 9.81 m/s2.arrow_forwardThe kitchen had a temperature 46 degrees Fahrenheit and was converted it to Kelvin. What is the correct number for this temperature (46 F) on the Kelvin scale?arrow_forward
- Water is traveling at a speed of 0.65 m/s through a pipe with a cross-section radius of 0.23 meters. The water enters a section of pipe that has a smaller radius, only 0.11 meters. What is the speed of the water traveling in this narrower section of pipe?arrow_forwardA particular water pipe has a radius of 0.28 meters. If the pipe is completely filled with water, moving with average velocity 0.45 m/s, what is the flow rate of water through the pipe with units of cubic meters of water per second?arrow_forwardWater is flowing through a horizontal pipe with two segments. In one segment, the water flows at a speed v1 = 4.52 m/s. In the second segment the speed of the water is v2 = 2.38 m/s. Based on Bernoulli's Principle, what is the difference in pressure (P2 - P1) between the two segments? Assume that the density of the water is 997 kg/m3 and give your answer as the number of Pascals (i.e. N/m2).arrow_forward
- Water from the faucet is supplied to the hose at a rate of 0.00057 m3/s. At what speed (number of meters per second) does the water exit the nozzle if the cross sectional area of the narrow nozzle is 2.1 x 10-6 m2?arrow_forwardJason Fruits/Indiana University Research Communications Silver/ silver oxide Zinc zinc/oxidearrow_forwardCar P moves to the west with constant speed v0 along a straight road. Car Q starts from rest at instant 1, and moves to the west with increasing speed. At instant 5, car Q has speed w0 relative to the road (w0 < v0). Instants 1-5 are separated by equal time intervals. At instant 3, cars P and Q are adjacent to one another (i.e., they have the same position). In the reference frame o f the road, at instant 3 i s the speed o f car Q greater than, less than, or equal to the speed of car P? Explain.arrow_forward

Car Q starts from rest at instant 1, and moves to the west with increasing speed. At instant 5, car Q has speed w0 relative to the road (w0 < v0). Instants 1-5 are separated by equal time intervals. Sketch and label a vector diagram illustrating the Galilean transformation of velocities that relates velocity of car P relative to the road, velocity of car Q relative to road, and velocity of car Q relative to car P at instant 3. In the frame of car P, at instant 3 is car Q moving to the west, moving to the east, or at rest? Explain.arrow_forwardJust 5 and 6 don't mind 7arrow_forward
