Answer:
Approximately .
Assumption: air resistance is negligible.
Explanation:
Make sure all the values are in standard units.
.
The bounce here is an inelastic collision between the ball and the surface. Some of the kinetic energy (KE) was lost. The exact value of energy loss would be equal to .
Before the bounce, all the kinetic energy of the ball would come from the drop from . That is:
.
After the bounce, the ball travels to a height of . All the potential energy gained in that process should come from the kinetic energy when the ball bounces back from the ground.
.
Hence, the size of energy loss due to the bounce would be equal to
.
Rocks and Continental shapes because if you put the continents together they will be very close to match and if you find a fossil (like south america) and a fossil in africa they will be the same animals . <span />
I think it is either a Foot trap or trap
Linear momentum of an object is the product of the object’s mass and velocity. Linear momentum is a vector quantity, and the direction of momentum is taken to be the direction of the object’s velocity.
or an object with mass moving at a velocity , the angular momentum with respect to a reference point is defined using the cross product as:
where is the position vector of the object that describes the object’s position with respect to the reference point. The units for measuring angular momentum is kg m2 s-1. Since angular momentum is defined in terms of a cross product, the direction of the angular momentum vector is taken to be in a direction perpendicular to both the particle’s position vector and its velocity vector .
