W
X
Y
IZ
Which object has the greatest acceleration?
34
Ow
OZ

Answer 1

X

Step-by-step explanation:

v=u+at but t is constant so

a=v-u

for x

a=29-10

a=19

which marks the greater acceleration

Answer 2

Y

Step-by-step explanation:

The answer is y because,

W: (29-11)/6 = 3

X: (34-10)/12 =2

Y: (40-12)/7=4

Z= (28-20)/8=1

4 is greater then all, therefore the answer is Y
