A cheetah can go from the state of rest to running at 20m/s in just two seconds. What is the Cheetahs average acceleration
babymother [125]

acceleration = change in velocity/change in time

so...

a = 20 m/s / 2 seconds

a = 10


hope that helps :)

P.S. found this from Brainly User, sometimes all you have to do is search to find the answer.

Zero, a hypothetical planet, has a mass of 4.5 x 1023 kg, a radius of 3.2 x 106 m, and no atmosphere. A 10 kg space probe is to
jok3333 [9.3K]

a.) K 2=K 1 +GmM( r 21− r 11)=2.2×10 7J

b.) ​K 2 +GmM( r 11− r 21)=6.9×10 7 J

Applying Law of  Energy conservation :

K 1+U 1

=K 2+U 2

⇒K 1− r 1GmM

=K 2− r 2 GmM

where M=5.0×10 23kg,r1

=> R=3.0×10 6m and m=10kg

(a) If K 1​

=5.0×10 7J and r 2

=4.0×10 6 m, then the above equation leads to

K 2=K 1 +GmM (r 21− r 11)=2.2×10 7J

(b) In this case, we require K 2

=0 and r2

=8.0×10 6m, and solve for K 1:K 1

​=K 2 +GmM (r 11− r 21)=6.9×10 7 J

A building superintendent twirls a set of keys in a circle at the end of a cord. If the keys have a centripetal acceleration of
maria [59]

Answer:

5.75m/s

Explanation:

The formula we need to use here is the formula of centripetal acceleration given as

a=v^{2} /r

we have the acceleration and the radius (luckly in the units we need them to be)

replacing it would yield

114m/s^{2} =v^{2} /0.29m

then solving for v

\sqrt{114m/s^{2} * 0.29m }= v

\sqrt{33 m^{2} / s^{2}}= v\\ 5.75 m/s = v

(notice how m/s^{2} * m yields m^{2}/s^{2} which when applying the square root yield m/s)
