An astronaut stands by the rim of a crater on the moon, where the acceleration of gravity is 1.62 m/. To determine the depth of

leva [86]

Answer;

=32.15 meters

Explanation;

Use the formula

s= ut+ 0.5 a (t)^2 to find out 's'

where s= distance traveled

u=initial velocity which is zero in this case

t= time taken to travel 's' distance

a=acceleration (due to gravity on moon i.e 1.62 m/s^2 )

Therefore;

S = 0.5 * 1.62 * 6.3 * 6.3

= 32.1489 meters

Thus; the crater is 32.15 meters deep.

A 900 kg car speeds up from 30 M/S to 80 m/s how much momentum did the car gain?

AlexFokin [52]

The change in momentum of the car is 45,000 kg m/s

Explanation:

The change in momentum of an object is given by:

$\Delta p = m(v-u)$

where

m is the mass of the object

u is its initial velocity

v is its final velocity

For the car in this problem, we have

m = 900 kg

u = 30 m/s

v = 80 m/s

Therefore, the change in momentum is:

$\Delta p = (900)(80-30)=45,000 kg m/s$

Describe the relationship between a moving objects mass and its kinetic energy

swat32

Kinetic energy is the energy of mass in motion, the kinetic energy that an object has is because of it's motion.Heavier objects that are moving have more kinetic energy than lighter ones.
