A grenade of mass 0.60 kg is at rest on a frictionless surface when it explodes into 3 pieces.
The first piece has a velocity of 4.0 m/s [E] and a mass of 0.25 kg. The second piece has a
velocity of 7.5 m/s [W 30.0° S] and a mass of 0.10 kg. Find the mass and velocity of the third
piece.

Show Calculation. Thank You :)

car stops. he keeps going = he has inertia

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
