Hope this helps Have a good day
for any ray on the mirror, incident angle - reflected angle.
angles wrt a normal to mirror
Slowing down, a stopping bike.
Speeding up, opening a door.
Constant but changing direction, the moon's orbit
Constant with no acceleration, the seconds hand on a clock.
See the bullet will have a parabolic path both the components should be solved separately thus the y-axis path will be a free fall as there won't be any velocity vector there
so we get
√2h/g= t
√2*78.4/9.8 = t
thus t= 4sec
it means it would take 4 sec to travel 1500 metres
so 1500/4 = 375 m/s would be velocity !
Answer:
a)
b)
c)
d) Treat the humans as though they were points or uniform-density spheres.
Explanation:
Given:
- mass of Mars,
- radius of the Mars,
- mass of human,
a)
Gravitation force exerted by the Mars on the human body:
where:
= gravitational constant
b)
The magnitude of the gravitational force exerted by the human on Mars is equal to the force by the Mars on human.
c)
When a similar person of the same mass is standing at a distance of 4 meters:
d)
The gravitational constant is a universal value and it remains constant in the Universe and does not depends on the size of the mass.
- Yes, we have to treat Mars as spherically symmetric so that its center of mass is at its geometric center.
- Yes, we also have to ignore the effect of sun, but as asked in the question we have to calculate the gravitational force only due to one body on another specific body which does not brings sun into picture of the consideration.
