1.) On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 6 iron. The
acceleration due to gravity on the moon is 1/6 of its
value on earth. Suppose he hits the ball with a
speed of 27 m/s at an angle 60 ° above the
horizontal.
A. How much farther did the ball travel on the moon than it would have on earth? B. for how much time was the ball in flight?

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Ray 2 should cross through the focal point on the right side of the lens.

Wouldnt it be millileter

D=m/v m=d*vd=densitym=massv=volumed(ether)=0.71 gr/cm³=0.71 gr/ mlv=130 mlm=d*vm=0.71 gr/ml*(130 ml)=92.3 gm=92.3 g
