- The star turned once to the left. The star turned once to the right A star is dilated with a scale factor of 2 and then reflected over the x-axis. Select all the final transformations of the stars. The star shifted to the right The star shifted to the left. The star flipped upside down The star flipped side ways The star is smaller The star is larger
- A ball of mass 4m is dropped from rest from a height h=10.0m above the ground, as shown above. It undergoes a perfectly elastic collision with the ground and rebounds. At the instant that the ball rebounds, a small piece of clay of mass m is released from rest from the original height h directly above the ball as shown above on the right. The clay, which is descending , eventually collides with the ball, which is ascending Assume that g= 10m/s^2 air resistance is negligible , and the collision process takes negligible time. a. Determine the speed of the ball immediately before it hits the ground. b. Determine the time after the piece of clay is released at which the collision takes place. c. Determine the height above the ground at which the collision takes place. d. Determine the speeds of the ball and the piece of clay immediately before the collision. e. If the ball and the clay stick together on impact, what is the magnitude and direction of their velocity immediately after the collision?
- Which of these observations does NOT provide evidence for the heliocentric model of our solar system? Planets move in elliptical orbits. Comets move in regular elliptical orbits Venus shows phases,just like the Moon Earth's gravitational pull keeps its moon in orbit.
