An airplane travels 622.4 km from Kansas City to St. Louis. The flight takes 4.7 hours. Calculate the Velocity of the plane

Why do some scientists not use controlled experiments?

A car has a mass of 1500 kg and a kinetic energy of 23,500 J. How fast is the car going?

1. A 930-kg car traveling 56 km/h comes to a complete stop in 2.0 s. What is the force exerted on the car during this stop?

The mass of a block is 8g and the volume is 4ml. A) Calculate the density of the block. Show your work.

A body starts from rest and moves with a uniform acceleration of 4m/s2 until it travels a distance of 800m, find the find velocity?

A transfer by work from the system, an elevation decrease of 50 m, and an increase in velocity from 15 m/s to 30 m/s. The specific internal energy, u, decreases by 5 kJ/kg and the acceleration of gravity is constant at 9.7 m/s².

What is the best prediction for the weather on the day after high pressure system passes

Is it possible to have motion in the absence of a net force?

There are 2 charged particles, A and B. You know that particle A is positively charged. When you place particle B next to particle A, then particle B starts moving away from particle A. What does this mean for particle B?

The speed of light is now to be defined 2.99792458x10^8 m/s express the speed of light to three significant figures five significant figures seven significant figures
