How does an inclined plane trade force for distance??

Physics
1 answer:
liq [111]3 years ago

The sloping surface of the inclined plane<span> supports part of the weight of the object as it moves up the slope. As a result, it takes less </span>force<span> to move the object uphill. The </span>trade<span>-off </span>is<span> that the object must be moved over a greater </span>distance<span> than if it were moved straight up to the higher elevation.</span>

A 35kg cannonball sits at rest on a flat level surface. What is the normal force exerted on the cannon ball. Use -9.8 m/s2 for a
Tom [10]

Answer:

a) N = 343 [N]

Explanation:

We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.

N=m*g

where:

m = mass = 35 [kg]

g = gravity acceleration = 9.81 [m/s²]

N = 35*9.8\\N= 343 [N]

A 50.0-kg crate is being pulled along a horizontal smooth surface. The pulling force is 10.0 n and is directed 20.0° above the h
steposvetlana [31]

Answer:

0.188 m/s^2

Explanation:

Assuming the crate does not lift above the ground and remains along the floor, then its acceleration will be in the horizontal direction. Therefore, we can use Newton's second law to find its acceleration:

F_x = ma_x

where

F_x is the net force on the crate along the x-direction

m is the mass of the crate

a_x is the acceleration

Here we have:

m = 50.0 kg

F_x = F cos \theta = (10.0 N)(cos 20.0^{\circ})=9.4 N is the component of the pulling force along the horizontal direction

Solving for the acceleration,

a_x = \frac{F_x}{m}=\frac{9.4}{50.0}=0.188 m/s^2
