A 65-kg ice hockey goalie, originally at rest, catches a 0.145-kg hockey puck slapped at him at a velocity of 35 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came.**Diagram Explanation:**The provided diagram illustrates the momentum and velocity of the hockey puck and goalie before and after a collision:- **Before Collision:** - The puck, with mass \( m_p \), is moving towards the goalie with an initial velocity \( v_{pi} \). - The goalie, with mass \( m_g \), is initially at rest, so \( v_{gi} = 0 \).- **After Collision:** - The puck is reflected back with a final velocity \( v_{pf} \). - The goalie moves forward with a final velocity \( v_{gf} \).### Key Concepts:- **Elastic Collision:** A collision in which both momentum and kinetic energy are conserved.- **Subscripts:** - \( i \) and \( f \) represent initial and final velocities, respectively. - \( p \) and \( g \) denote the puck and the goalie.This scenario presents a real-world application of physics principles such as conservation of momentum and elastic collisions, illustrating how different masses can affect velocity outcomes during interactions.

1. A 65-kg ice hockey goalie, originally at rest, catches a 0.145-kg hockey puck slapped at him at a velocity of 35 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. A sketch from the animation from Part 1 should look like this. Note the subscripts i and f indicate velocities before and after the collision, respectively. The subscripts p and g represent the puck and the goalie, respectively.

1. The launcher is set to launch a projectile horizontally. Once launched, the projectile will immediately go into the pendulum (the “catcher” in the diagram), causing the pendulum to swing. Considering momentum, sum all the momenta of the situation after the ball is launched but before it goes into the pendulum. Do not consider the recoil of the launcher. 2. When the ball gets caught by the pendulum, what kind of collision is this (elastic or inelastic)? What is the momentum after the collision? Using conservation of momentum, derive an equation for the velocity of the ball/pendulum combo immediately after the ball is caught (and before the pendulum starts to swing upward). The equation can depend on the mass of the ball, the mass of the pendulum, and the initial velocity of the ball. 3. The pendulum will start to swing upwards. At the beginning of its swing, what kind ofenergy does the pendulum have? It will swing up to a certain angle where it will temporarily stop. What kind of…

Use vectors to solve the following problems. Both cars weigh 1500 kg. Use the scale 1 cm = 1,000 kg x m/s. Assume all collisions to be elastic and sticking. Draw a picture represents the problem too. The first car is travelling at 20 m/s east. The second car is travelling at 30m/s north. Using vectors draw to scale the component vectors and the resultant from their collision. Then solve using your trigonometric functions. Also: use Pythagorean Theorem
