The potential energy of an apple is 6.00 joules. The apple is 3.00-meters high. What is the mass of the apple?

1 answer:

8 0

Potential energy = (mass) x (gravity) x (height)

Divide each side by (G x H) : Mass = PE / (G x H)

PE = 6 joules
Gravity = 9.8 m/s
Height = 3 m
 Mass = 6 / (9.8 x 3) =

 6 / (29.4) = 0.204 kg

(weighs about 2 newtons or 7.2 ounces on Earth)

Fiesta28 [93]

Answer: 9.375m/s

Explanation: This is an inelastic collision, so the formula is mv1+mv2=(m1+m2)v-final. My work is a follows:

2500kg(12m/s) + 700kg(0m/s)=(2500kg+700kg)(v-final)

30,000kg(m/s)+0=3200kg(v-final)

30,000kg(m/s)/3200kg=9.375m/s

The particle of 2 velocities 10m/s due east and 12m/S in the direction 30N/E. What is the resultant velocity and the direction?

Paha777 [63]

Answer:

See below

Explanation:

East components are 10 and 12 cos 30 = 20.392 m/s

North component = 12 sin 30 = 6 m/s

Resultant velocity = sqrt ( 20.392^2 + 6^2) = 21.26 m/s

direction arc tan (6/20.392) = 16.4 degrees N of east

Since V is 5 times larger than C

A) 0V = 25C

25C to 0C = -25
-25 / 5 = -5

so 0C = -5 V

B)

20V x 5 = 100 C
