On planet #4, you fire a projectile from the ground at an initial speed of 29.7 m/s at an angle of 58.4 degrees above the horizontal. The projectile lands 53.2 m away from the launch point. What is the value of g for planet #4?

An airplane releases a ball as it flies parallel to the ground at a height of h = 215 m as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height h from the release point, calculate the speed v of the plane. Neglect any effects due to air resistance, and use g = 9.81 m/s² for the acceleration due to gravity. h U = m/s

A physics student stands on a cliff overlooking a lake and decides to throw a softball to her friends in the water below. She throws the softball with a velocity of 24.5 m/s at an angle of 31.5° above the horizontal. When the softball leaves her hand, it is 12.5 m above the water. How far does the softball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer. Macmillan Learning horizontal distance: E

In the Marvel comic series X-Men, Colossus would sometimes throw Wolverine toward an enemy in what was called a fastball special. Suppose Colossus throws Wolverine at an angle of 0 = 23.0° with respect to the ground (see figure below). Wolverine is d = 2.14 m above the ground when he is released, and he leaves Colossus's hands with a speed of v; = 22.6 m/s. d (a) Using conservation of energy and the components of the initial velocity, find the maximum height attained by Wolverine during the flight. m (b) Using conservation of energy, what is Wolverine's speed the instant before he hits the ground? m/s
