Answer:
x=5
Step-by-step explanation:
change to x=12-7
subtract
x=5
Answer: false
Step-by-step explanation: Compare -5 and -32. They do not equal each other.
That would depend on how many vehicles there are. The question is not complete.
Answer:
No idea sorry we have not learned this yet
Use the kinematics equation:
v1^2-v0^2=2as
since v1=0 (at height of 81 ft), and a=g=-32.2, substitute values:
0-v0^2=2*(-32.2)(81 ft)
Solve for v0
v0=sqrt(2*32.2*81)=72.2 m/s
