Is the driver exceeding the speed limit of 75.0 ?mi/h b) What if the driver were from outside the United States and is familiar with speeds measured in kilometres per hour? What is the ?speed of the car in km/h

You ride your bike for 1.5 h at an average velocity of 10 km/h, then for 30 min. at 15 km/h. a) What is your average velocity in km/h. b) What is your velocity in m/s. c) What is your velocity in miles per hour (mph)

Two roads intersect at right angles. Elizabeth, who is driving east, leaves the intersection traveling at a speed of 40 mph. Two hours later, Nairi leaves the same intersection at a speed of 30 mph heading north. How fast is the distance between the cars changing five hours after Elizabeth leaves? Homework Help

Physics question

On a fishing trip on Lesser Slave Lake you drive your motorboat north at 20.0 km/h for 30.0 minutes. After realizing that you passed your fishing spot, you turn south and travel at 35 hm/h for 10.0 minutes. Determine your average. a) speed for this trip. [24km/h] b) velocity for this trip. [ 6.3 hm/h, North]

A truck is moving at +35.0 m /s when the driver sees a red light. In 2.60 seconds, the truck comes to a stop. A. Find the truck's acceleration (magnitude and direction). B. Find the truck's displacement(magnitude and direction).

8) Two ships are 10 km apart and moving toward each other at 6.0 km/h and 4.0 km/h, respectively. A bird flies continuously back and forth between them at 20 km/h. What is the total distance traveled by the bird when the ships meet? I need to show all works physics flow chart

A car is traveling due East at a rate of 36.2 kph and a train is due North at a speed of 74.70 kph and bound to meet at an intersection 1 km for the train and the car. a. Determine the acceleration of the car, If the car reaches the intersection 10 seconds ahead of the train. b. Determine the velocity of the car at the intersection.

4) While Prof. K. was stuck in airport over break, she saw someone riding a Modobag (the world's first motorized carry-on luggage) and immediately ordered one off Amazon. Once it got delivered, she took it for a test ride up the hill between the Student Union and the football stadium. Prof. K. started traveling with an unknown initial velocity and came to a complete stop after 25 ft. a) Clearly draw coordinate systems for Prof. K. travelling up the hill. Write out the necessary transformation arrays. b) Draw an FBD and IRD for the system. c) Rolling friction is a function of normal force, just like regular friction would be, therefore Frolling=Crr*N. Develop a symbolic equation for the friction force, Frolling, of the bag in terms of the other forces on the FBD (i.e. develop an expression for "N") d) The coefficient of rolling resistance, Crr between the wheels and the ground is equal to 0.0295. The combined weight of Prof. K. an her packed Modobag is 180 Ibs. and the angle 0 = 15°.…
