A mining cart is pulled up a hill at 24 km/h and then pulled back down the hill at 31 km/h through its original level. (The time required for the cart's reversal at the top of its climb is negligible.) What is the average speed of the cart for its round trip, from its original level back to its original level?
An automobile travels on a straight road for 40 km at 45 km/h. It then continues in the same direction for another 35 km at 40 km/h. (a) What is the average velocity of the car during this 75 km trip? (Assume that it moves in the positive x direction.)
A car travels along a straight line at a constant speed of 56.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 27.0 mi/h. (a) What is the constant speed with which the car moved during the second distance d? mi/h (b) Suppose the second distance d were traveled in the opposite direction; you forgot something and had to return home at the...
A car travels along a straight line at a constant speed of 53.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 31.0 mi/h what the constant speed with which the car moved during the second distance d? suppose the second distance d were traveled in the opposite direction: you forgot something and had to return home at the same constant speed as...
What is the average speed, in km/h, for a car that travels 23 km in exactly 15 min?
A car traveling 70 km/h slows down at a constant 0.47 m/s2 just by "letting up on the gas." Calculate the distance it travels during the fifth second. Express your answer to two significant figures and include the appropriate units.
A car travels due east with a speed of 55.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 75.0° with the vertical. Find the velocity of the rain with respect to the following reference frames. (a) the car km/h (b) the Earth km/h
