pogonyaev3 years ago
3 0

Answer:

vf²=vi²+2a∆x

Explanation:

The third equation of motion gives the final velocity of an object under uniform acceleration given the distance traveled and an initial velocity: v 2 = v 0 2 + 2 a d . v^2=v_0^2+2ad. v2=v02+2ad. The graph of the motion of the object.

What is the gravitational force between two trucks, each with a masof 2.0x10^4 k
eduard

Answer:

6.67\cdot 10^{-3} N

Explanation:

The gravitational force between two objects is given by

F=G\frac{m_1 m_2}{r^2}

where

G is the gravitational constant

m1, m2 are the two masses

r is the separation between the two masses

In this problem, we have

m_1 = m_2 = 2.0 \cdot 10^4 kg the mass of each truck

r = 2.0 m is their separation

Substituting,

F=(6.67\cdot 10^{-11}) \frac{(2.0\cdot 10^4 kg)^2}{(2.0 m)^2}=6.67\cdot 10^{-3} N

What is the power of a machine that transfers 15,000J of energy in 1 minute?
____ [38]

Answer:

answer is 250 W

Explanation:

W=P * t

t=60s

W= 15000J

15000= P * 60

P= 15000/60

P= 250W. (SI unit of power Watt)
