Explaination needed with the answer please Earth is rotating about the Sun in our solar system. The distance between the Earth and Sun is 1.5 × 1011m. Consider the impact of an asteroid of mass 8.9 ×1015 kg and a speed of 90,000 km/h with respect to the Earth’s surface. The asteroid strikes the Earth at the equator as shown in Figure. Consider the mass and radius of the Earth are ME = 5.97 × 1024 kg and RE = 6.38 ×106 m, respectively. Assume that the axial and orbital axis of rotations are parallel to each other. (A) What is the maximum possible change in the length of a day due to the collision? (B) How much energy is needed to stop the Earth’s rotation about its axis after the collision?

Queston 7 (int Listen Hew lones it take a CDnnine radr rotate an angle of 4680 018 Qukstion 8 Listen The Earth takes one day to complete one rotation about the axis passing through its poles.

I only need help on 1C) I don't understand how i can get my answer close to 70.7 m/s   i don't understand what I'm missing when I've tried findind the angular speed(w) as (v/r) but that only gives me a very small number and when changing the equation to v=wr doesn't seem to help either   I'm not sure what I'm doing wrong, please show and explain to me, thank

c. Ground level 2 being the next fastest, etc. If two disks have the same center of mass speeds, give them the same ranking. Free Response Question Three disks are initially placed at the top of an incline and released from rest. They each roll without slipping down the incline. Disk A has mass M and radius R, disk B has mass 2M and radius R, and disk C has mass M and radius 2R. Disk A Disk B Disk C a. Rank the disks from greatest to least based on their total kinetic energy at the bottom of the incline, with 1 being the most energy, 2 being the next most energy, etc. If two disks have the same total kinetic energy, give them the same ranking. Justify your ranking. c. Your teacher uses wax on the incline to decrease friction to the point where disk A is rolling and slipping down the incline. How does the speed of the center of mass of disk A at the bottom of the waxed incline compare to what it is when it was rolling without slipping? A. Greater with slipping B. Greater without…

I Review Constants Periodic Table (Figure 1) In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall.. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. Part A What is the minimum rotational frequency, in rpm, for which the ride is safe? Express your answer in revolutions per minute. Figure 1 of 1 • View Available Hint(s) f = rpm Submit
