An object of mass 2 kg rests on the floor, as shown in the picture. A force of 45 N, making an angle of 60° to the vertical, is applied to move the object. What is the acceleration of the object in the horizontal direction?

1. how to locate the image in converging(concave) mirror and diverging (convex) mirror with salt. 2. how to locate the image in a converging (convex) lens and diverging (concave) lens with salt.

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four
