An astronaut drops a feather from 1.2 m above

Physics
1 answer:
vfiekz [6]4 years ago

This is a free fall and in free fall we use this formula:

d = (1 ÷ 2) × g × t², where d is the distance, g is the gravitational acceleration and t is the time.

In our case,

We are already given the moon's gravitational acceleration and we are going to substitute it with g. Let's leave the unknown alone, which is t.

t = √(2d ÷ g)

If we perform the formula, t is found to be √(2d ÷ g) = √(2 × 1.2 ÷ 1.62) ≅ 1.217 s

I am sorry for my bad English and if there is anything that you do not understand please let me know.

A negative slope on the velocity vs. time graph indicates that the object is not
Svetlanka [38]

Answer: False, I think

Explanation:

Well it depends. Its hard to say without a function of the graph. Given a velocity graph, the first derivative is the acceleration.

Negative slope on a velocity graph means you are going in the negative direction. And over time, your velocity per unit of time is also decreasing. That means we are accelerating in the negative direction

Danielle exerts a 14.0 N force to compress a spring by a distance of 8.00 cm. What is the spring constant of this spring
Lady_Fox [76]

Answer:

175 N/m

Explanation:

Given:

Force = F=  14.0 N

Distance = x = 8.00 cm = 0.08 m

To find:

spring constant

Solution:

spring constant is calculated by using Hooke's law:

k =  F/x

Putting the values in above formula:

k = 14.0 / 0.08

k = 175 N/m
