How far will 490 J of work raise a block weighing 7 N?

To find the height a block can be raised using 490 J of work, we can use the formula for work: ( W = F \cdot d ), where ( W ) is work, ( F ) is force (weight of the block), and ( d ) is the distance (height raised). Rearranging the formula gives ( d = \frac{W}{F} ). Substituting the values, we have ( d = \frac{490 , \text{J}}{7 , \text{N}} = 70 , \text{m} ). Therefore, the block can be raised 70 meters.


How far will 350 J raise a block weighing 7 kg mass?

To find out how far 350 J of energy will raise a 7 kg block, we can use the formula for gravitational potential energy: ( PE = mgh ), where ( PE ) is potential energy, ( m ) is mass, ( g ) is the acceleration due to gravity (approximately 9.81 m/s²), and ( h ) is the height. Rearranging the formula to solve for height gives us ( h = \frac{PE}{mg} ). Substituting in the values, we have ( h = \frac{350 , \text{J}}{7 , \text{kg} \times 9.81 , \text{m/s}^2} \approx 5.1 , \text{m} ). Therefore, 350 J will raise the block approximately 5.1 meters.


Is 4.9 cm more or less than 490 mm?

There are 10 mm in a cm. So 4.9 cm is only 49 mm, far less than 490 mm.


How far will a car move that weighs 1342 when hit by another car weighing 697 going 60 mph?

How far is a 500 ft in a city block?

In a city, a standard city block is typically about 1/8 of a mile, or approximately 660 feet. Therefore, 500 feet is roughly three-quarters of a city block. However, the exact distance can vary depending on the specific layout of the city.
