Question

2.16* A golfer hits his ball with speed v at an angle & above the horizontal ground. Assuming that
the angle is fixed and that air resistance can be neglected, what is the minimum speed vä(min) for
which the ball will clear a wall of height h, a distance d away? Your solution should get into trouble if
the angle is such that tan <h/d. Explain. What is v(min) if 0 = 25°, d = 50 m, and h = 2 m?

Hi, I have one more follow-up question regarding a similar problem where I need to find the height: In a rollercoaster ride a passenger car at the top of the first hill is travelling at 3.5 m/s. The carthen descends on rails to the bottom of the slope and then goes up the second hill where the speed is 10 m/s. Find the difference in height between the first and second hill. (Result 4.47m) Attached is the formula I tried to use, however, I get a different result so I am definitely doing something wrong. Online I didn't find a similar problem so I am asking here as a last chance. Can you help?
How would I begin to solve this problem? In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket's position measured from the center of the Earth is given by y(t) = (RE3/2 + 3*(g/2)1/2 REt)2/3 where RE is the radius of the Earth (6.38 ✕ 106 m) and g is the constant acceleration of an object in free fall near the Earth's surface (9.81 m/s2). (a) Derive expressions for vy(t) and ay(t). (Use the following as necessary: g, RE, and t. Do not substitute numerical values; use variables only.)
A projectile is launched towards a hill that is d=252m away. The launch angle is θ=51.7∘ above the horizontal with an initial speed of v0=71.5m/sv0=71.5m/s. The hill can be approximated as a plane sloped at φ=27.1∘. Neglect air resistance. 1. Write an equation for y as a function of x, d, and φ for the line that defines the slope of the hill. 2. Write an equation for y as a function of x, g, v0, and θ of the trajectory of the projectile. 3. What is the x coordinate, in meters, of the landing spot of the projectile?
