According to Newton's first law of motion, what would happen to a car traveling at a constant velocity of 55 MPH to the west in

mart [117]

Explanation:

Newton's first law of motion says that an object will be at rest or it will be in motion until an unbalanced force acts on it.
In this case, a car traveling at a constant velocity of 55 mph to the west in the absence of an unbalanced force.

It would mean that the car will continue to move with a constant velocity of 55 mph to the west due to Newton's first law of motion.

A swan on a lake gets airborne by flapping its wings and running on top of the water. If the swan must reach a velocity of 6.00

ira [324]

Answer:

A. 51.42 m.

B. 17.14 s.

Explanation:

Using equations of motion:

vf^2 = vi^2 + 2 * aS

Where,

vf = final velocity

a = acceleration

S = distance to which swan traveled

vi = 0 m/s

6.00^2 = 2 * 0.350S

S = 36/0.7

= 51.42 m.

vf = vi + at

6 = 0 + 0.35t

t = 6/0.35

= 17.14 s.

A satellite is put in a circular orbit about Earth with a radius equal to 35% of the radius of the Moon's orbit. What is its per

Debora [2.8K]

Answer:

0.21 lunar month

Explanation:

the radius of moon = r₁

time period of the moon = T₁ = 1 lunar month

The radius of the satellite = 0.35 r₁

Time period of satellite

The relation between time period and radius

$T\ \alpha\ \sqrt{r^3}$

now,

$\dfrac{T_2}{T_1}=\dfrac{\sqrt{r_2^3}}{\sqrt{r_1^3}}$

$\dfrac{T_2}{T_1}=\dfrac{\sqrt{0.35^3r_1^3}}{\sqrt{r_1^3}}$

$\dfrac{T_2}{1}=\sqrt{0.35^3}$

T₂ = 0.21 lunar month

hence, the time period of revolution of satellite is equal to 0.21 lunar month
