PHYSICS

If a ball is thrown upwars with a velocity of 75 feet per second, what is its velocity at the end of 1.6 seconds

( g = 32.2 ft/sec2) ? Velocity: V = Vo - gl

=75 - ( 32.2 x 16) = 23.48 ft/sec.

Height: S	=	Vol - 1/2 gl2
	=	(75 x1.6)– (1/2 x 32.2 x (1.6 )2 )
	=	78.784 ft.

Trigonometric Functions

In this right triangle,

A = 5.7 feet and a = 30 degrees. Determine the value of C.

sin a =	A/C	5.7/C
sin 30	degrees =	5.7/C
C = 5.7 / sin 30 degrees
C = 5.7 / 5
C = 11.4
