![1] You fire a 50 gram arrow that moves at an unknown speed. It hits and embeds in a 450 gram block that slides on an air track. At the end, the block runs into and compresses a 4000 N/m spring 0.2m. (Friction ignored) (i) Draw a labelled sketch before the spring gets compressed. Circle the system you choose (ii) Draw a labelled sketch after the spring gets compressed. Circle the system you choose (iii) Use conservation of linear momentum before the spring gets compressed to relate initial velocity of the arrow and common velocity of arrow-block (iv) Draw energy bar chart when the arrow-block runs into and compresses the spring (v) Use work-energy principle to find the common velocity of arrow-block. (vi) Find the initial velocity of the arrow with which it hits the block.](http://img.homeworklib.com/questions/0c053200-5f6e-11eb-80d2-639adf3481be.png?x-oss-process=image/resize,w_560)

PROBLEM 2 (5 points). Momentum and Mechanical Energy conservation A rifle bullet with mass 150 g strikes and embeds itself in a block with mass 1000 g that rests on a frictionless, horizontal surface and is attached to a coil spring. The initial velocity of the bullet was 700 m/s. The impact compresses the springy a distance x. The spring constant is 550 N/m. The spring is ideal. a) Find the magnitude of the block's velocity (with the bullet stuck...

1. A 1200kg car traveling at 11.0 m/s runs into a 920kg car traveling in the same direction at 5.00 m/s. After the collision the 1200kg car has slowed to 8.00 m/s. a) what is the final velocity of the 920kg car? 2. A bullet mass of m=0.0010kg embeds itself in a wooden block with mass M=0.999kg, which then compresses a spring (k=230 N/m) by a distance x=0.050m before coming to rest. The coefficient of kinetic friction between the block...

2m 20 1m You have built an enormous spring-loaded Hot Wheels track that will propel a 50 gram toy car through a loop and launch it across the room. The spring constant is 800 N/m, the spring launcher has an initial spring displacement of 5 cm. What is the maximum radius R of the loop such that the car moves around the loop without falling off at the top, so that the toy car can make to the end point...

OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
