PLEASE TRY TO ANSWER AS MANY QUESTIONS AS YOU CAN ! 1) Carrie pulls a 41.5 kg bin across the floor of her garage using a rope that is attached to the bin. She pulls with a force of 138 N, at an angle of 28.0° above horizontal. The coefficient of kinetic friction between the floor and the box is 0.290. What is the acceleration of the box?

2) Alistair places a 6.40 kg block on an inclined plane that is 23° above the horizontal. The block starts from rest, and in 2.20 seconds, travels 1.40 m. What is the force of friction on the block?

3) A 1.45 kg box is placed on a ramp that is 21° above the horizontal. If the coefficient of static friction is 0.49, and the coefficient of kinetic friction is 0.32, what will happen to the box?

4) Kevin works as a janitor, and he is pushing a fully-loaded recycling bin that weighs 557 N across the floor. He applies a force of 410 N at an angle of 15° below the horizontal. The coefficient of kinetic friction between the recycling bin and the floor is 0.46. How long does it take him to move the bin 6.5 meters, assuming the bin starts from rest?

5) Clarissa accidentally throws her 165 g flying disc onto the roof of her house. The roof is at an angle of 30° above the horizontal. If the disc sits motionless on the roof, what is the force of friction acting on the disc?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
