A ball is thrown vertically upwards from a height of 8 ft with an initial velocity of 30 ft per second. How high will the ball go? Note that the acceleration of the ball is given by a(t)= -32 feet per second per second a) 50.1875 ft
b) 18.5469 ft
c) 53.1875 ft
d) 22.0625 ft
e) 34.1875 ft

c)

Step-by-step explanation:

u = Initial velocity = 30 ft/s

s = Displacement

v = Final velocity = 0

a = Acceleration due to gravity =

From kinematic equations we have

Distance the ball will reach from the height from which the ball is thrown is .

Distance of the ball from the ground is .

answer is c

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
