PART ONE

Physics
1 answer:
puteri [66]4 years ago
3 0

Explanation:

Impulse = change in momentum

F Δt = m Δv

F (31 s) = (320 × 0.006 kg) (4.6 sin 70° m/s − (-4.6 sin 70° m/s))

F = 0.535 N

Pressure = force / area

P = F / A

P = 0.535 N / 1.455 m²

P = 0.368 Pa

A ball with the mass of 600kg moves at a speed of 8 m/s legatos force is needed to bring it to a stop at 10 s
lorasvet [3.4K]

Answer:

480N

Explanation:

A ball is moving a speed of 8 there fore it had to be add force opposite direction to the ball if it takes to rest. There for ball is subjected to deceleration. First we can find the deceleration

V = U + at

0 = 8 + a×10

a= 0.8 m /s²

Then we can apply newton's 2nd law to determine the force acted by legatos

F= ma

F= 600×0.8

  = 480 N

A transport plane takes off from a level landing field with two gliders in tow, one behind the other. The mass of each glider is
Rom4ik [11]

Answer:

Length = 155.6 m

Explanation:

given data

mass = 700 kg

total resistance = 4300 N

tension = 12000 N

speed = 40 m/s

solution

we get here equation for glider in the back  and front  

for the glider in the back

T - 2400 = 700 a    ...........1

for the glider in front

12000 - T - 2400 = 700a    .............2

now we add both  these equations

12000 - 4800 = 1400 a     .............3

a = 5.14 m/s²

and

now we use equation of motion

v² - u² = 2 a S    .............4

40² = 2 × 5.14 × S

so  

Length = 155.6 m

Do you think there might be a point in space between Earth and the Moon where the gravity of each would pull on an object equall
Firlakuza [10]

Answer: Yes.

Explanation:

Assuming Earth and Moon are isolated is space, it is possible to have a point where Earth and Moon will pull at an object with equal force.

That point will be closer to the Moon than the Earth because Moon's gravitational field strength is weaker than Earth's gravitational field strength.
