Question

explain

1. A marble is fired into the air at 12m/s at an angle of 35° from vertical. It lands 1.25 m lower than its launch height. What is the maximum height that it reaches above its landing location? When does it reach this height? When does it land? What is its velocity (speed and direction) when it lands? Max height Time at max height = Time of landing- Velocity at landing - 2. The Space Shuttle used to fly at an altitude of up to 650 km. What is the gravitational acceleration at this altitude? The mass of the Earth is 5.97 x 1024 kg and its radius is 6370 km. If a mass were dropped from rest at this altitude, how fast would it be going after it had fallen 1 mile (1.61 km)? Gravitational acceleration - Speed- 3. A massless spring is used to launch a 0.25 kg ball directly upward. The spring has a spring constant of 450 N/m and is compressed by 0.67 m. The ball is placed on the spring, and then the spring is released. How fast is the ball traveling when it leaves the spring? How high will the ball go? Think about energy principles. Speed - Height-
