No. Speed is speed and force is force.
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.
Answer:The atmosphere directly absorbs about 23% of incoming sunlight, and the remaining energy is transferred from the Earth's surface by evaporation (25%), convection (5%), and thermal infrared radiation (a net of 5-6%).Jan
Explanation:
None
Answer:
The magnitude of the vertical component of its velocity as it hits the ground is 30 m/s. The horizontal distance from the firing point is 750 meters.
