Q1. After a tornado, a 0.60 straw was found embedded 2.7 into the trunk of a tree. If the average force exerted on the straw by the tree was 85, what was the speed of the straw when it hit the tree?

Q2. A baseball is bunted down the third-base line leaving the bat from a height of 0.850m with an initial velocity of 4.00m/s at an angle of 37.87° above horizontal

a) what is the speed of the baseball just before hitting the ground? (Answer by using mechanical energy conservation)

b) What is ball's normal (centripetal) acceleration at the maximum height?

c) What is baseball's tangential acceleration at maximum height?

d) Reply b and c for the instant just before the ball hits the ground

e) what are the radiuses of the baseball path curvature at the greatest height and the point of grounding.
