t= 2.25 secs
Step-by-step explanation:
Step 1 :
Equation for motion with uniform acceleration is v = u+ at
where v is the final velocity
u is the initial velocity
a is the acceleration due to gravity
and t is the time
Step 2 :
Here , v = 0 because at the highest point final velocity is 0.
u = 72 feet/sec
a = -32 ft/sec^2
We need to find the time t.
Substituting in the equation we have,
0 = 72 -32 * t
=> 32 t = 72
=> t = 72/32 = 2.25 secs
Answer:
12
Step-by-step explanation:
Answer:
answer is A. cosine
Step-by-step explanation:
17/8 -11/3
51/24-88/24
-37/24 simplified is -1 13/24
-2a from both sides then divide by -5 and a=1
