Answer:
Initial velocity = 10 m/s
θ = 60°
This is the case of projectile motion
So the horizontal component of velocity 10 m/s = 10 cosθ
u = 10 cosθ
u = 10 cos 60°
u=5 m/s
x= 5 m
So in the horizontal direction
x = u .t
5 = 5 .t
t = 1 sec The vertical component of velocity 10 m/s = 10 sinθ
Vo= 10 sinθ
Vo= 10 sin 60°
Vo = 8.66 m/s
h=3.75 m
So height of robot = 3.75 - 0.75 m
height of robot =3 m
Answer:
It would mean less transpiration and the groundwater would start to make a landslide with no tree root to hold the earth in place
Answer:
The answer is C because there is no friction there will be no friction force only applied and since its on ice you have to account for gravity
Explanation:
The answer is B.
Temperature is just another term for the average kinetic energy of a substance.
True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
