Awad of clay of mass m1 with an initial horizontal velocity v1 hits and adheres to the massless rigid bar which supports the body of mass m2, which can be assumed to be a particle. the pendulum assembly is freely pivoted at o and is initially stationary. determine the angular velocity ˙ of the combined body just after impact. why is linear momentum of the system not conserved?

scientific laws are the result of testing theories and proving them to be facts.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
