1.-Una fuerza horizontal de 40 N es apenas suficiente para poner en marcha un trineo de 600 N sobre nieve compacta. Después de empezar el movimiento se requieren tan solo 10 N para mantener el trineo a rapidez constante. Halle los coeficientes de fricción estática y cinética

A900 kg roller coaster car is travelling westward on the track and begins to slow down from 18m/s to 2m/s. how long does it take the roller coaster car to decelerate if the force acting on the car to slow it is 7024n? how far does the roller coaster travel during this time?

Amass has an acceleration of 10- 2t. what is its velocity and displacement if it started at x- 4m and the initial velocity was 8m/s? at what time does it have 0 velocity? graph all graphs.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?
