The shot put world record for women stands at 22.63 m (Natalya Lisovskaya, 1987). Assuming that the shot is projected from a height of 2.2 m at an angle of 45° and neglecting air resistance, the initial speed of the particle is 14.22 m/s. Use g = 9.81 ms-2 for the gravitational acceleration on the surface of the Earth. Parameters (x(+)), z(+)): Vo x(+) 늘 = 2(+) = 글 gta Vo t + √√2 + Zo 1. Find the maximal height of the shot, using the parameters. Give a general expression (no numbers substituted in yet), then evaluate this expression to 2 digits accuracy. 2. Eliminate time t to find an implicit expression of the form z(x) of the solution curve. Use this expression to again determine the maximal height of the shot. 3. Use conservation of energy to determine the maximal height of the shot. You should find the same answer with all three methods.

A space shuttle lands on a distant planet where the gravitational acceleration is 2.0 ( We do not know thelocal units of length and time , but they are consistent throughout the problem). The shuttle coasts along aleve, frictionless plane with a speed of 6.0. It then coasts up a frictionless ramp of height 5.0 and angle 0f 30°.After a brief ballistic flight, it lands a distance S from the ramp. Solve for S in local units of length. Assume theshuttle is small compared to the local length unit and that all atmospheric effects are negligible. Use x and y components.

A golf coach is showing her athletes how to hit a golf ball from the ground. Using her driver, she hits a golf ball with an initial velocity of 250 ft/sec at an angle of 11.5 with the ground. After the ball hits the ground, it rolls for another 63 feet. While the ball is in air, it can be modeled with the parametric equations: z(t) = v, cos (e) t, y(t) = - 16t² + sin(e) t with z(t) as the horizontal position of the ball after tseconds y(t) as the vertical position of the ball after tseconds to as the initial velocity 8 as the initial launch angle A. How long is the ball in the air before it first hits the ground? B. How far does the ball travel, including after it rolls to a stop? Use mathematics to justify your answers. Show your work in the space provided.

Problem: A person who is 1.3 m tall throws a ball with a speed of 19m/s at an angle of 17 degrees above horizontal. One part of the problem asks me to find the x and y components of the ball's velocity before it hits the ground. I have tried using the vy^2 = voy^2 + 2ah for the y-component: vy^2 = (5.56)^2 + (2)(10)(1.3) = 7.54 and my x-component is just (19)(cos(17))= 18.17 m/s, but it is saying this is not the right answer. What am I doing wrong?
