The answer is (c) I believe.
Because the same of 1500kg has to be the same number of the force 1500N
If there's not any number above to specify.
nthomas2594

Answer: D.)

Weight is a force and is calculated by multiplying mass(kg) by an acceleration(m/s²). The acceleration caused by Earth's gravity is 9.8m/s² (sometimes simplified as 10m/s². The SI unit of acceleration is meters per second *squared*. The SI unit for force(weight) is Newtons(N).

1500kg • 10m/s² = 15,000N

more specifically:

1500kg • 9.8m/s² = 14700N

So the answer would be D.)
