Why is NASA still using some equipment from the 1960s?

a
NASA has a fixed budget that is less funding than they had during the space race.
b
The machinery is efficient, so the next generation of engineers didn't waste time designing a new one.
c
Brevard county doesn't collect enough taxes for them to build a new one.
d
It has never broken, so why replace it. They built a very good product back then.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
