Susie rides down and to the right on a slide for a total displacement of -3m at an angle of 45 degrees above the ground. What wa

Svetlanka [38]

Susie's vertical displacement is 2.1 m

Explanation:

In order to solve this problem, we have to resolve the displacement vector along the vertical direction.

The vertical component of a vector is given by:

$v_y = v sin \theta$

where

v is the magnitude of the vector

$\theta$ is the angle between the direction of the vector and the horizontal

Therefore, the vertical component of the displacement in this problem is given by

$d_y = d sin \theta$

where

d = 3 m is the magnitude of the displacement

$\theta=45^{\circ}$ is the angle between the displacement and the horizontal

Substituting, we find

$d_y = (3)(sin 45^{\circ})=2.1 m$

on the surface of planet x a body with a mass of 10 kilograms weighs 40 newtons. The magnitude of the acceleration due to gravit

tamaranim1 [39]

Based on the Newton's second law of motion, the value of the net force acting on the object is equal to the product of the mass and the acceleration due to gravity. If we let a be the acceleration due to gravity, the equation that would allow us to calculate it's value is,
W = m x a
where W is weight, m is mass, and a is acceleration. Substituting the known values,
40 kg m/s² = (10 kg) x a
Calculating for the value of a from the equation will give us an answer equal to 4.
ANSWER: 4 m/s².
