A car cover a distance of 5m in 3 hours. calculate the velocity in (1) km/hour (2) m/s​

The velocity of a curling stone is due east. what will be the direction of the momentum of the curling stone as it moves?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
