Suppose that an object whose is 10th weighs 50 N find the weight of an object whose is 6 kg

Nady [450]

Weight is another term for the force from mass multiplied by acceleration due to gravity, the equation being expressed as $f = ma$ , being force, mass, and acceleration respectively.

We already have 2 parts of the equation, $50 = 10a$

Acceleration due to gravity on the planet is $5 m/s^2$

Plug it into the equation $f = ma$

$f=6kg$ x $5m/s^2$

Weight or force from gravity is 60N.

A basketball player made 40% of the shots she attempted.if she made 32 baskets, how many shots did she attend?

malfutka [58]

32 divde by 2 = 16 (50%)
32 divde by 10 = 3.2 (10%)
16 - 3.2 = 12.8 (40%)
3.2 times 4 = 12.4 (40%)

You would round the number to the nearest whole because you can't make a . of a shot. Therefore the answer would be that she made 12 shots.

Hope this helps!
