Solve Part D please
Learning Goal: To understand how the conservation of energy and Newton's second law can be combined to solve kinetic problems. As shown, a large globe has a radius R and a frictionless surface. A small block with mass m starts sliding from rest at the top of the globe and slides along the globe's surface. The block leaves the globe's surface when it reaches a height h above the ground. The system's geometry is shown for...

Problem: Learning to fly In this example, we will apply conservation of energy, including potential energy, together with Newton’s laws and the expression for the acceleration in the radial direction of an object moving on a circular path. A young fledgling bird of mass m is sat at the very top of a dome, which is circular in cross section of radius R. Starting with an initial velocity of zero, the bird starts to slide down the dome. There is...

Derive the expression for the initial velocity v of a ballistic pendulum in terms of the swept-out angle theta. Use the following equations of momentum and energy conservation... When the projectile and the pendulum stick together, they have total mass m + M and we define their combined velocity to be V⃗ . The relationship from conservation of momentum is: mv = (m + M)V⃗ Conservation of energy requires the initial kinetic energy of the pendulum system to equal the...

#13) multi-question. Provided useful equations.
Question 13 [8] A baseball player slides to 3rd base. A friction force (1) acts against his motion as indicated in the figure. He needs to slide a distance d of 2.5 m to be safe. (a) Use the work-energy theorem with non-conservative forces to write down an equation to find the actual distance the player slides. (b) If he starts sliding with an initial velocity of 5.0 m/s and the coefficient of kinetic friction...

Use the work–energy theorem to solve each of these problems. You can use Newton’s laws to check your answers. A)A skier moving at 4.25 m/s encounters a long, rough, horizontal patch of snow having a coefficient of kinetic friction of 0.220 with her skis. How far does she travel on this patch before stopping? B)Suppose the rough patch in part A was only 2.89 m long. How fast would the skier be moving when she reached the end of the...
