Force= mass*acceleration
Force=1610*14.2=22862N

Answer:

20 N exerts no torque about the pivot.

14 N exerts a counterclockwise torque of 14 * .3 = .42 N-m

6 exerts a clockwise torque of 6 * .7 = .42 N-m

The meter stick will not turn because there is no net torque on the meter stick.

You throw a ball with a mass of 0.50 kg against a brick wall. It hits the wall moving horizontally to the left at 20 m/s and reb

Orlov [11]

Answer:

The value of impulse of the net force on the ball during its collision with wall is $I = 15\ kg \frac{m}{s}$

The value of average horizontal force that the wall exerts on the ball during the impact is F = 15000 N

Explanation:

Mass of the ball = 0.5 kg

Horizontal velocity $V_{x}$ = 20 $\frac{m}{s}$

Velocity after collision $V_{-x}$ = - 10 $\frac{m}{s}$

(A). Impulse of the net force on the ball during its collision with wall is

$I = m (V_{x} - V_{-x})$

I = 0.5 × (20 + 10)

$I = 15\ kg \frac{m}{s}$

This is the value of impulse of the net force on the ball during its collision with wall.

(B). The magnitude of average horizontal force

$F = \frac{I}{T}$

Where F = Force

I = impulse & t = time interval = 0.001 sec

$F = \frac{15}{0.001}$

F = 15000 N

This is the value of average horizontal force that the wall exerts on the ball during the impact.

A car is travelling at 20m/s, accelerates at 4m/s2 . Calculate its velocity after 5s?

IgorLugansk [536]

Answer:

Explanation:

The final velocity of an object that experiences a period of acceleration is given by:

v - vi = A*t

Initial velocity, vi, is = 20m/s

Acceleration, A, is 4m/2^2

Time, t, is 5 seconds

v - vi = A*t

v - 20m/s = (4m/2^2)/(5 sec)

v = (20 m/s) + (20 m/s)

v = 40 m/s

What is the mass of a skier if they are applying a force of 500N and they are accelerating at 20m/s2?

Brrunno [24]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

We know that,

$force = mass \times acceleration$

$500 = m \times 20$

$m = \dfrac{500}{20}$

$m = 25$

Mass of skier is <u>25</u> kg
