A diver jumps off a cliff of height h at an angle θ = 260 (see figure). He reaches a maximum height of h subscript m a x end subscript= 20 m above the top of the cliff before falling to the water below. He hits the water x=295 m from the base of the cliff. Determine the height of the cliff, h. Take g=10m/s2 . Round your answer to one decimal place.
A stunt plane flying at the Reno Air Races is moving through the sky. The rectangular coordinates describing its motion are: x = -0.74t3 + 2.5t2 + 10.25t y = -6.23t2 + 16.45t + 8.94 where x and y are given in ft and t is given in seconds. a) Calculate the velocity vector, v, and acceleration, a, of the plane after 10 seconds (velocity is in ft/s and acceleration is in ft/s²). You may want to look back at your Topic 2 notes to recall how position, velocity, and acceleration are related. Your final answer should be given in vector form. b) Calculate the magnitude of the velocity (in mph) and the acceleration (in ft/s²) at t = 10 sec in mph. [Ans. to Check: v = 132.46 mph]

A cannonball is shot with an initial speed of 42 m/s and 37.0° angle with respect to the ground. How long does it take for the ball to reach its the maximum height, in seconds? Use g = 10.0 m/s. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
A rocket follows a path givent by y=x-1/40 x^3(in miles). The horizontal velocity is given by Vx=x, find the Magnitude and the Direction of the velocity when the rocket hits the ground (assuming level terrain) if time is in minutes. The magnitude is approximately ? miles per minute (rounded the final answer to one decimal point. Round all intermediate values to two decimal places as needed. The direction of the velocity is in degrees.
