Babe Ruth steps to the plate and casually points to left centerfield to indicate the location of his next home run. Themighty Babe holds his bat across his shoulder, with one handholding the small end of the bat. The bat is horizontal, andthe distance from the small end of the bat to the shoulder is22.5cm. If the bat has a mass of 1.1kg and has a center ofmass that is 67vm from the small end of the bat, find the magnitudeand direction of the force exerted by: a) the hand
b) the shoulder.

What is the angular momentum of the bar about the axle?

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
