Lisa is conducting an investigation to determine the coefficient of friction between two surfaces. she uses a 25 kg block. what is this object's weight, in newtons?

Weight, W = 245 N

Explanation:

It is given that,

Mass of the block, m = 25 kg

We need to find its weight. From Newton's second law of motion,

a is the acceleration of the object

On the surface of earth,

F = 245 N

So, the weight of the object is 245 N. Hence, this is the required solution.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
