Answer:

Explanation:
As we know that average velocity is defined as the ratio of total displacement of the object and its time interval.
so here we can say

now we know that in one complete revolution the total displacement of the tip of the seconds hand is zero
because it will have same position after one complete revolution from where it starts
so here we can say that the average velocity will be zero

Answer:
pumpkin
Explanation:
watermelon and pumpkins are close to shape and size
Answer:
Explanation:
mass (m1) = 1150 kg
mass (m2) = 1900 kg
impulse (J) = 200 N.s
With what relative speed do the two parts separate because of the detonation?
since both parts separate, their relative speed = speed of m1 + speed of m2
- speed of m1 =
=
= 0.174 m/s
- speed of m2 =
=
= 0.105 m/s - relative speed = 0.174 + 0.105 = 0.279 m/s
This is mr day and infact am seeing this… come into my office after class.
