Am going nuts If a vehicle has a mass of 750 kg
a) What is its weight on earth? Take gravity to be 10 Nkg-1
b) If the gravity on the moon is 1/6th that of the earth, calculate the weight of the car on the moon
c) Given that F = ma, calculate the force needed to move the vehicle with an acceleration of 5ms-2.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
