I creating another composite to jump one-quarter as high as the initial composite you most bear in mind factors of weight,hardness ,center of mass will be one-quarter of the prior composite in other for it to bounces only one-quarter .

From the question we are told

A composite when tested bounces half as high as the original material. How can you create another composite that bounces only one-quarter as high

Generally We know that

A composite Material is a material that is made up of more than be substance i.e is it requires substance of variant properties and make up to come together to form it.

Therefore

Answer:

Explanation:

The question relates to motion on a circular path .

Let the radius of the circular path be R .

The centripetal force for circular motion is provided by frictional force

frictional force is equal to μmg , where μ is coefficient of friction and mg is weight

Equating cenrtipetal force and frictionl force in the case of car A

mv² / R = μmg

R = v² /μg

= 26.8 x 26.8 / .335 x 9.8

= 218.77 m

In case of moton of car B

mv² / R = μmg

v² = μRg

= .683 x 218.77x 9.8

= 1464.35

v = 38.26 m /s .

A child sleds down a hill with an acceleration of 2.94 m/s2. If her initial speed is 0.0 m/s and her final speed is 17.5 m/s, ho

Answer:

The child will take 5.952 seconds to travel from the top of the hill to the bottom.

Explanation:

Given that the child accelerates uniformly and that both initial ( $v_{o}$ ) and final speeds ( $v_{f}$ ), measured in meters per second, and acceleration ( $a$ ), measured in meters per square second, are known, we proceed to use the following kinematic equation to determine the time taken to travel from the top of the hill to the bottom ( $t$ ), measured in seconds, is:
