Alex

Answer: 42 N-s

Explanation: The area under the curve is equal to the impulse, so you take the area of the two triangles and add it to the area of the rectangle.

Area of a triangle: 1/2bh

Area of a rectangle: bxh

2(1/2x2x7)=14+(4x7)=42 N-s

A 4.0 kilogram object is dropped from a height of 1.0 meter onto a spring with a spring constant of 850 newtons per meter. Appro

lisov135 [29]

Answer:

(1) 3.0 dm

Explanation:

Due to the law of conservation of energy, the initial gravitational potential energy of the object will be all converted into elastic potential energy of the spring as the object hits the spring:

$mgh = \frac{1}{2}kx^2$

where

m = 4.0 kg is the mass of the object

g = 9.8 m/s^2 is the acceleration due to gravity

h = 1.0 m is the initial height of the object

k = 850 N/m is the spring constant

x is the compression of the spring

Solving the equation for x, we find:

$x=\sqrt{\frac{2mgh}{k}}=\sqrt{\frac{2(4.0 kg)(9.8 m/s^2)(1.0 m)}{850 N/m}}=0.30 m=3.0 dm$
