An object is projected horizontally at 14.1 m/s from the top of a 195.0 meter cliff. How far from the base of the cliff will the object strike the ground?

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

answer; how far out of place which the object finished relative to the starting location;

it would be c. predictability

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.
