Answer:

-2040 m/s²

Explanation:

Taking toward the wall to be positive, the initial velocity is 10.1 m/s and the final velocity is -8.3426 m/s.

Average acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (-8.3426 m/s − 10.1 m/s) / 0.00905 s

a = -2040 m/s²

Jason applies a force of 4.00 newtons to a sled at an angle 62.0 degrees from the ground. What is the component of force effecti

Andreas93 [3]

Answer: 1.88 N

Explanation:

Data:

Force = 4.00N
angle = 62°
horizontal force = ?

Solution:

The trigonometric ratio that relates horizontal - leg to hypotenuse is the cosine.

That ratio is:

                        horizontal - leg
cos(angle) = -------------------------
                          hypotenuse

So, applied to the force, that is:

                             horizontal force
cos (angle) = -----------------------------------
                                 total force

So, clearing the horizontal component you get:

horizontal force = force * cos (angle)

Substitute the data given:

horizontal force = 4.00N * cos(62°) = 4.00N * 0.4695 = 1.88 N

A 0.25 ball is thrown with the speed of v=4.5m/s at a resting stick that can rotate around one end at the axis O. The ball hits

malfutka [58]

Answer:

$\mathbf{^\to Q =0.84375 \ (- \hat z) \ kgm^2s^{-1}}$

Explanation:

mass of the ball = 0.25 kg

its speed v = 4.5 m/s

r = 0.75 m

let the speed be in the horizontal direction and the distance r be in the vertical direction we have :

$^ {\to}v = 4.5 \ x \ \ m/s$

$^ {\to}r = 0.75 \ y \ \ m/s$

Let the momentum about the center of intersection be P;

SO;

$^ \to} P = ^{\to} mv$

$^ \to} P = 0.25* 4.5 \ x \ \ m/s$

$^ \to} P = 1.125 \ x \ \ m/s$

Let the angular momentum be Q;

$^\to Q = ^ \to r* ^ \to P$

$^\to Q = (0.75*1.125) kgm^2s^{-1} *(\hat y * \hat x)$

$\mathbf{^\to Q =0.84375 \ (- \hat z) \ kgm^2s^{-1}}$
