Ksenya-84 [330]

Answer:

3859 grams

Explanation:

Given: Weight of a television = 8.50 pounds

To find: Weight of a television in grams

Solution:

1 pound = 0.454 kg and 1 kg = 1000 g

So,

1 pound = 0.454 × 1000 = 454 grams

8.50 pounds = 8.50 × 454 = 3859 grams

Therefore,

Weight of television in grams = 3859 grams

A 16.0 g bullet is moving to the right with speed 250 m/s when it hits a target and travels an additional 22.6 cm into the targe
bogdanovich [222]

Answer:

The magnitude will be "2212 N".

Explanation:

The given values are:

Initial speed, u = 250 m/s

Final speed, v = 0

Mass, m = 16.0 = 0.016 kg

Distance, d = 22.6 cm

On converting cm into m, we get

d = 0.226 m

As we know,

⇒  v^2-u^2=-2ad

⇒  a=\frac{v^2-u^2}{-2d}

On putting the estimated values, we get

⇒    =\frac{(0)^2-(250)^2}{-2\times 0.226}

⇒    =\frac{0-62500}{-0.452}

⇒    =13,8276 \ m/s^2

Now,

Force, F=ma

On putting values, we get

⇒            =0.016\times 138276

⇒            =2212 \ N (magnitude)
