Aball of mass 0.5 kg is released from rest at a height of 30 m. how fast is it going when it hits the ground? acceleration due to gravity is g = 9.8 m/s²

During your summer internship for an aerospace company, you are asked to design a small research rocket. the rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 910 m above the earth's surface. the rocket's engines give the rocket an upward acceleration so it moves with acceleration of 16.0 m/s2 during the time t that they fire. after the engines shut off, the rocket is in free fall. ignore air resistance.

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called
