Answer:
18000 Bg
Explanation:
after 15 minutes = 36000/2
After 30 minutes = 36000/4
30 minutes × 2 = 1 hour
After 1 hour = 36000/4 × 2 = 18000 Bg
Answer:
a) Fg = m* g
b) Fg = 58.86 N
c) pointing down (towards the center of the Earth)
d) N = 58.86 N
e) pointing up
Explanation:
a) Force is defined as mass of the object times the acceleration it is subjected to. In our case, the block is subjected to the acceleration of gravity (g), therefore the force due to gravity (Fg) is Fg=m*g
b) perform the indicated product of part a):
Fg = m*g = 6 kg * 9.81 m/s^2 = 58.86 N
c) since the object is not moving, that means that the contact force exerted by the surface were the block is resting, must equal the acting force of gravity, but pointing in opposite direction, so the NET force on the block is zero. Therefore, the magnitude of the normal force (N) must equal the magnitude of the object's weight: N = 58.86 N
d) As explained in part c), the normal force must be acting in opposite direction to the force of gravity, which means pointing up.
Acceleration = change of velocity over the time = (16-4)/8=1.5 m/s^2
<span>The distance "d" you bike varies directly with the amount of time "t" you bike. Therefore,
d </span>α t
To turn it into equality, we introduce k, proportionality constant.
d = kt
We find the value of k from the given conditions. <span>Suppose you bike 13.2 miles in 1.25 hours.
13.2 = k(1.25)
k = 10.8 miles/our
Therefore the equation would be:
d = 10.8t
It is a linear graph with slope 10.8 and it passes at the origin.</span>
