question 1:
D) 245 m BECAUSE -Y = V0y - 1/2gt2 and V0y = 0
so Y= (1/2)(10)(7)2 = 245 m
D) 245 m BECAUSE -Y = V0y - 1/2gt2 and V0y = 0
so Y= (1/2)(10)(7)2 = 245 m

question #2 is ...
c) 36m
This is because accelaration is change in velocity/change in time.
So (16-4)/(3-0) = 4 m/s^2
Put in 3 sec makes 4m/s^2=Xm/(3)^2
Solve for X, X= 36m.
