Recall that
where and are the lion's initial and final vertical velocities, is its acceleration, and is the vertical displacement.
At its maximum height, the lion has 0 vertical velocity, so we have
where <em>g</em> is the acceleration due to gravity, 9.80 m/s², and we take the starting position of the lion on the ground to be the origin so that .
Let <em>v</em> denote the initial speed of the jump. Then
B (9.81 m/s^2)
Speed no, because acceleration isn't 0
Velocity, pretty much same as speed
Distance no, because it's getting closer
Because they have different density (density of feathers < density of nails)
Answer:
When net force of zero acting on a ball which is at rest , then the object center of mass will not accelerate , but the object may begin to rotate .
Explanation:
Here when there is an object where several forces are acing upon are zero then the center of mass will not accelerate because we know that
Where acceleration of center of mass
= net force = 0
So the acceleration of center of mass will be zero
But the torque ,may not be zero as torque is product of individual force and perpendicular force .
Since if torque is not equal to zero then the object may begin to rotate
Answer:
F = 20.07 μN
Explanation:
given,
intensity of sunlight = 667 W/m²
area of surface = 9.03 m²
speed of light = 3 x 10⁸ m/s
force = ?
we know
force =
force =
F = 20.07 x 10⁻⁶ N
F = 20.07 μN
