  • " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "

  • Rock Thrown horizontally, with a velocity of 10 m/s, from a bridge

    When the rock hits the water and we solve for the time of the fall: (1.2) In the horizontal direction there is no force, hence the horizontal velocity is constant and equal the initial horizontal velocity The distance the rock travels

  • Projectile motion-initial speed

    0 + ½ a t ^2=½ g t ^2 since u=0 , no initial velocity and acceleration in the downward direction = acceleration due to gravity=g=9.81 m/s^2 Time taken for the rock to hit the water =t y=½ g t ^2 y=40 40=1/2 * 9.81 * t ^2

  • Velocity, Force, and Acceleration

    NOTE: assume he does not hit bottom. (3) If you throw a 44 kg rock off of a cliff, how fast does it accelerate to the ground? The earth exerts a force of 200 Newtons on the rock.

  • Heat, harmonics, power, calories, efficiency, velocity, wave

    What is the blocks temperature after it was raised? a. Less than it was after it fell b. This can't be determined c. 20 degrees C, the same as it was before it fell 10. Waves travel 5000m/s along a wire that is 2m long.

  • Physics: Density, Vectors, Speed, Acceleration, Velocity

    The speed of sound in air (at the ambient temperature) is 336 m/s. Solution: Let the depth of the water surface in the well be h and time taken for the rock to hit water surface be t1.

  • Gravity and Projectile Motion

    He gives it an initial velocity of 20 m/s at an angle 34 degrees above the horizontal. The height of the cliff is 30 m, and the rock takes 8.0 s to hit the ground below the cliff. (A) How far from the base of the cliff did the rock hit?
