Question

Work the following problems completely. (Make logical physics statements and show your calculations) 41. Abowling ball, moving to the east at a speed of14m/s, collides head-on with a stationary beach ball of the same diameter but with one twentieth the mass. After the collision, the beach ball moves with a speed of 1.6 m/s. Calculate the velocity of the bowling ball 42. An oil tanker heading due west, straightinto a strong wind, reaches a speed of5 m/s and then shuts down its engines to drift. The forward-facing flat surfaces of the tanker catch a total of 60,000 N of force tons, which is This milion kg. If is pointing back at the same strength for mass how much has the from the 100 wind force the wind blows the The 5 minutes, then wind changed the tanker's speed?

Explanation / Answer

here,

the initial speed of bowling ball , u1 = 1.4 m/s

mass be balls are m and m/12

final speed of beach ball , v2 = 1.6 m/s

let the speed of bowling ball be v1

using conservation of momentum

m * u1 = m * v1 + m/12 * v2

1.4 = v1 + 1.6 /12

v1 = 1.27 m/s

the final speed of the bowling ball is 1.27 m/s
