- A bullet with mass m1 = 3 g is fired into a wooden block of mass m2 = 2 kg, that hangs like a pendulum. The bullet is embedded in the block (complete inelastic collision). The block with the bullet embedded in it goes h = 40 cm high after collision. Determine the speed of the bullet before it hit the block. a. 1570 m/s c. 1670 m/s b. 1870 m/s d. 1770 m/sQ3Two remote control cars with masses of 1.15 kilograms and 1.98 kilograms travel toward each other at speeds of 8.41 meters per second and 3.97 meters per second, respectively. The cars collide head-on, and the less massive car recoils with a speed of 2.25 meters per second.a. What is the final speed of the second car? b. How much kinetic energy is lost in this collision?
- 8. You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 3.3 kg, and the sleds mass is 10.1 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 5.48 m/s. What will be your speed on the ice after jumping off? 0.38 m/s 1.22 m/s 0.99 m/s 0.76 m/sYou are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 64.8 kg, and the sleds mass is 21.5 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 4.25 m/s. What will be your speed on the ice after jumping off? 0.71 m/s 2.12 m/s 1.77 m/s 1.41 m/sTwo trucks are approaching an extremely icy four way perpendicular intersection. Dennis is driving his 3100 kg truck northward at 22 m/s while Eddie drives eastward in his 1100 kg car. They collide and stick together, traveling at 59◦ north of east. What was Eddie’s original speed?
- A 17.8 kg sled is sitting at rest on level ice, and this sled is hit by another sled that is twice as massive. After the collision, the sleds stick together and move off at 6.3 m/s. How fast was the larger sled initially moving just before the collision?How do I solve this problem step by step?A student is driving a 1200 kg car at 42.0 m/s. He is tail-gating ("drafting") behind a 2500 kg truck that is going 40.0 m/s in the same direction as the car. (DON'T EVER DO THIS! IT IS EXTREMELY DANGEROUS AND ILLEGAL) The car collides with the truck and the two vehicles are stuck together. How fast are they moving after the collision?
- A 92 kg boulder , moving at 5.0 m/s attempts to pass directly across the adit of a mine. Just as the boulder reaches the end of the adit, it was met head-on in midair by two 75 kg miners, both moving in the direction opposite the boulder. One is moving 2.0 m/s, the other at 3.0 m/s . They all become entangled as one mass. What is their velocity after the collision? 18. What is the momentum of a 18 kg object traveling at a constant velocity that has 295 J of kinetic energy?1. A billiard ball, labeled 1, moving horizontally strikes another billiard ball, labled 2, at rest. Before the impact ball 1 was moving at a speed of 5.0000 m/s and after the impact it is moving at a speed of 3.0000 m/s at an angle of 50 degrees from the original direction. The two balls have equal mass.
