How long does it take a car to cross a 30 m wide intersection after the light turn green, if the car accelerates from rest at a constant 3.00 m/s2

Explanation:

Hello,

In this case, since the car starts from from rest whereas the initial velocity is zero, we can compute the time via the following equation:

Which is solving by applying square root:

Best regards.

which three statements are true about all alloys?

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.
