Calculate the gravitational force between the earth of mass 2.6 multiply 10 raise to power 9 and a book of 5.6multiply 10 raise to power 3 dropped on the ground , a distance of 4.2metre from the earth centre ​

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
