A soccer ball of 4.40925 (2 kilosg) pounds moves to the right a speed of 0.5 m/s.  Hits a 0.1102311 (0.05 kilosg) pounds tennis ball initially moving to the left at 2 m/s.  The collision is elastic and takes place in one dimension, along the x axis. What is the approximate final speed of the tennis ball, vf,g?

A 100-g bat collides with a stationary 1.2 kg teddy bear. Immediately after the collision, the bat is traveling at an angle of 55 degrees from its original path. The bear is traveling in a direction 35 degrees from the original path of the bat. (All the motion occurs in two dimensions). If the bear is moving at 0.060 m/s immediately after the collision, how fast is the bat moving after the collision?

A joelshawon is a subatomic particle with a mass of 5.7 g, and it is made out of a joelon (mass 2.7 g) and a shawon (mass 3 g). A joelon going 7.2 × 10° m/s to the east collides with a shawon going 6.9 x 106 m/s to the north. Determine the speed and direction of the resulting joelshawon. peed: rection: degrees north of east

A 20 gg ball of clay traveling east at 2.0 m/sm/s collides with a 20 gg ball of clay traveling north at 2.0 m/sm/s.   What is the speed of the resulting 40 gg ball of clay? Express your answer with the appropriate units.

Janet is skating at the ice rink with her little sister Sarah who is initially standing at rest on the ice. Janet then collides head-on into Sarah. Janet continues forward at 2 m/s, while Sarah is thrown backward at 3 m/s. (After the collision, Janet and Sarah are moving in the same direction). Janet’s mass is 54 kg and Sarah’s mass is 34 kg. How fast was Janet moving initially, in m/s?

A young 45 kg45 kg ice hockey goalie, originally at rest, deflects a 0.14 kg0.14 kg hockey puck slapped at him at a speed of 34.5 m/s34.5 m/s. In this problem, take the original direction of the puck as positive. Suppose the goalie and the hockey puck have an elastic collision and the puck is reflected back in the direction from which it came. What would the final velocity, in meters per second, of the goalie be in this case?

A 99 g steel ball bearing rolls to the right at 172 cm/s and makes an elastic head-on collision with another steel ball bearing with a mass of 72 g that is initially at rest. After the collision, the 99 g ball moves at 48.47 cm/s. a.The final velocity of the 72 g ball bearing in SI units is b.

A soccer ball of 4.40925 (2 kilosg) pounds moves to the right a speed of 0.5 m/s.  Hits a 0.1102311 (0.05 kilosg) pounds tennis ball initially moving to the left at 2 m/s.  The collision is elastic and takes place in one dimension, along the x axis. What is the speed of the center of mass, vcm?

A 10.50-g bullet is fired into a stationary block of wood having mass m = 4.980 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.6090 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.) O 289.449

Two cars collide at an intersection. Car A�, with a mass of 1900 kgkg , is going from west to east, while car B�, of mass 1300 kgkg , is going from north to south at 14.0 m/sm/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 55.0 ∘∘ south of east from the point of impact.How fast were the enmeshed cars moving just after the collision?
