A2 kg block is pushed against a spring (k = 400 n/m), compressing it 0.3 m. when the block is released, it moves along a frictionless, horizontal surface, and then up an incline that has friction (μs = 0.4 and μk = 0.2). how far up the incline does the block slide before coming to rest?

Explanation:

Given values  

Mass (m) = 2kg

K = 400 N/M

Compressing it 0.3 m

The law of conservation of energy:

Energy of the spring deformation.

M mass of the block

x spring deformation

Therefore, if block left the spring (x = 0)

Where, Δl is initial spring deformation

The law of conservation of energy:

Where h is height

Cancel mass "m" each side

Distance along incline equals

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
