Answer:
2 real solutions
Step-by-step explanation:
hello,
as this is > 0 there are 2 different real solutions
hope this helps
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
Since the growth was constant, we can find the time it took to grow 1 cm by dividing 10 by 16. 10/16 = 0.625 day to grow 1 cm.
To find the length in grew in one day - 16/10 = 1.6 cm in 1 day.
