Answer:

Mass is 152.95743

weight in ibs 3304.6914215069355 ibs

EXPLANATION:

1500 N = 152.95743 KG

152.95743 KG × 9.8 = 1498.982814

1 KG is 2.2 IBS

so

14o8.982814 is 3304.6914215069355

What happens to the position of an object as an unbalanced force acts on it? Give an example.
Evgesh-ka [11]

Hi! I'm a few days late since I just saw this question just now, but I'll answer anyway.

Answer:

When an unbalanced force acts on a moving object, the velocity of the object will change. Change in velocity means a change in speed, direction, or both. For example, if you kick a soccer ball and it moves from one place to another, it means that unbalanced forces are acting upon it. The ball moves from one place to another after kicking it so the position changed.

3a) w = mg = 60 x 10 = 600N
b) W = fd = 600 x 10 = 6000J
c) chemical to gravitational potential via the mechanical pathway

4a) W = fd = 200 x 0.5 = 100J
b) chemical to kinetic via mechanical pathway

5a) F = W/d = 40000/20 = 2000N
b) some is transferred into the thermal store, some is dissipated into the surrounding
