Why are astronauts weightless in the space station?
olga55 [171]

Answer:

Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.

A car travels on the entrance ramp to a freeway as it accelerates from 30 mph to the freeway speed of 70 mph for 4.0 s. Suppose
vova2212 [387]

Answer:

a) distance d = 293.36ft

b) acceleration a = 14.67ft/s^2

Explanation:

Acceleration is the change in velocity per unit time.

a = ∆v/t ....1

Given;

Initial velocity vi = 30mph × 5280ft/mile × 1/3600s/h

vi = 44ft/s

Final velocity vf = 70mph × 5280ft/mile × 1/3600s/h

vf = 102.67ft/s

time = 4.0s

From equation 1, acceleration is;

a = ∆v/t = (102.67-44)/4 = 14.67ft/s^2

Distance travelled can be given as;

d = ut + 0.5at^2 .....2

u = 44ft/s

t = 4

a = 14.67ft/s^2

Substituting into the equation 2

d = 44(4) + 0.5(14.67×4^2)

d = 293.36ft

Anissa slides down a playground slide sloped at 25o. The coefficient of kinetic friction between Anissa and the slide is 0.15. I
Keith_Richards [23]

Answer:5.62 m/s

Explanation:

Given

Inclination \theta =25^{\circ}

Coefficient of kinetic Friction \mu _k=0.15

mass of Anissa's m=55 kg

time interval t=2 s

acceleration of the system

a=g\sin \theta -\mu _kg\cos \theta

a=9.8\sin (25)-0.15\cdot 9.8\cos (25)

a=4.14-1.33=2.81 m/s^2

v=u+at

where v=Final Velocity

u=Initial Velocity

a=acceleration of system

t=time

v=0+2.81\times 2

v=5.62 m/s
