which of these is not a physical property of matter? select one: a. flammability b. color c. hardness d. density
netineya [11]
I believe the answer your looking for is A. Flammability. Because flammability is a chemical property, not a physical one. Hope this helps :)

an ice skater starts with a velocity 2.25 m/s in a 50.0 degree direction after 8.33s she is moving 4.65 m/s in a 120 degree dire
svetoff [14.1K]

Answer:

-0.032 m/s^2

Explanation:

To answer the question, we just need to consider the motion along the horizontal direction.

The component of the initial velocity of the ice skater along the x-direction is:

u_x = u cos \theta =(2.25)(cos 50^{\circ})=1.45 m/s

where u = 2.25 m/s is the initial velocity and 50^{\circ} is the angle.

The component of the final velocity of the ice skater along the x-direction is

v_x = u cos \theta =(4.65)(cos 120^{\circ})=-2.33 m/s

where u = 4.65 m/s is the final velocity and 120^{\circ} is the angle.

The acceleration along the x-direction is given by

a_x=\frac{v_x-u_x}{t}

where

t = 120 s is the time

Substituting,

a=\frac{-2.33-(1.45)}{120}=-0.032 m/s^2

B. Inelastic collision.

In elastic collision , both momentum and kinetic energy are conserved while in inelastic collision only momentum is conserved. there is some loss of energy in inelastic collision during collision.

During the collision of bat with baseball, some energy gets lost to heat and sound. hence the kinetic energy is not conserved although the momentum is conserved.

A 0.850 kg block is attached to a spring with spring constant 18 N/m . While the block is sitting at rest, a student hits it wit
Sveta_85 [38]

The block's speed at the point where x=0.25A is v = 31.95 cm/s.

<h3>What is Spring constant?</h3>

The spring stiffness is quantified by the spring constant, or k. For various springs and materials, it varies. The stiffer the spring is and the harder it is to stretch, the bigger the spring constant.

question is incomplete, this is the remaining statement

What is the amplitude of the subsequent oscillations? And What is the block's speed at the point where x=0.25A?

x = Asin(wt)

v = Aw coswt

at t = 0

w = sqrt(k/m)

v = Aw

A = v/w

A = 7.17 cm

part b )

E = 1/2mv^2 + 1/2kx^2 = 1/2kA^2

mv^2 + k(1/4A)^2 = 1/2kA^2

mv^2 + kA^2/16 = kA^2

mv^2 = kA^2 - kA^2/16

mv^2 = 15kA^2/16

v^2 = 15/16 * (k/m) * A^2

v^2 = 15/16 *w^2A^2

v = sqrt(15/16) * wA

v = 31.95 cm/s
