Answer:

The sled slides 0.68m before rest.

Explanation:

Vi= 2 m/s

m= 60kg

μ= 0.3

N= m * g = 60kg * 9.8 m/s²= 588 N

Fr= μ * N

Fr= 176.4 N

a= Fr/m

a= -2.94m/s²

t= Vi/a

t= 0.68 seg

d= Vi*t - a*t²/2

d= 0.68m

Sam is playing football. She kicks the ball with an average force of 75 N.
damaskus [11]

Answer:

22.5J

Explanation:

Here the force is given. Also, the displacement is given as 30cm.

First we should check if all the values are in their standard form.

Here 30cm should be converted to metre by dividing it with 100.

Which would give us 0.3m

Now we use the equation W=force x displacement =75 x 0.3=22.5J

I hope this satisfies you. If u have any further questions please let me know.

I hope u will follow me and make this the brainliest answer.

1. ¿Cuál es el actor clave de del exceso de peso corporal?
Slav-nsk [51]

El peso de un cuerpo es definido por la relación entre la energía requerida para los procesos vitales del cuerpo, sus actividades físicas diarias y la energía suministra en forma de alimentos.

Cuando estos dos parámetros están en balance el peso es estable, pero cuando la cantidad de alimentos aumenta o el valor energético de los mismo aumenta se tiene un exceso de energía que el cuerpo almacena en forma de grasa corporal, este el el factor mas importante para el exceso de peso.

En conclusión el factor mas importante para el exceso de peso es un  exceso de energía por una alimentación excesiva

Why is it difficult to measure the volume of gas
MrRissso [65]
It's difficult to measure that because it's hard to make sure it is only a uniform layer of gas in whatever you're measuring it in
