An SUV is traveling at a speed of 18 m/s.if the SUV had a mass of 1,550kg, what force must be applied to stop it in 8seconds?

1 answer:

6 0

To solve this question, we have to find the acceleration of the car first. Acceleration refers to the rate of change of velocity of an object with respect to time.
Acceleration [A] = [V0 - V1] / T
Where VO = Initial velocity and V1 = Final velocity T represent time.
V0 = O
V1 = 18
T = 8
A = [ 0 - 18] / 8 = - 2.25
A = - 2.25 M/S^2.
To find force, we are going to use the formula: F = MA
F = ?
M = 1550
A = - 2.25
F = 1550 * - 2.25 = 3487.5
Therefore, F = -3487.5 N

USPshnik [31]

Answer: $122.50

Step-by-step explanation:

In Out

8:00 12:00 = 4 hours

12:45 17:30 = 4.75 hours

Total 8.75 hours

8.75 hours x $14/hr = $122.50

Note: to subtract 12:45 from 17:30, borrow 1 hour from 17 and add 60 minutes to 30:

17:30 → 16:90

- 12:45 - 12:45

4: 45

4 hours 45 minutes = $4\frac{3}{4}$ = 4.75 hours

Answer:

a) Martín recorrió más distancia, b) A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente, c) La distancia recorrida promedio es 21.889 kilómetros, d) Martín recorrió 0.333 kilómetros más que Santiago.

Step-by-step explanation:

a) En primer lugar, convertimos la distancia recorrida por cada persona a su forma decimal:

Samuel

$\frac{178}{8}\,km = 22.25\,km$

Martin

$21\,km + \frac{3}{4}\,km = 21.75\,km$

Santiago

$21\,km + \frac{5}{12}\,km = 21.417\,km$

Como puede apreciarse, Martín recorrió más distancia.

b) La distancia faltante es igual a la sustracción de la distancia recorrida por la persona a la distancia total:

Samuel

$x = 29.3\,km -22.25\,km$

$x = 7.05\,km$

Martin

$x = 29.3\,km - 21.75\,km$

$x = 7.55\,cm$

Santiago

$x = 29.3\,km - 21.417\,km$

$x = 7.883\,km$

A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente.

c) La distancia recorrida promedio se obtiene sumando las distancias recorridas de las tres personas y dividiendo el resultado por la cantidad de personas:

$\bar{x} = \frac{22.5\,km + 21.75\,km + 21.417\,km}{3}$
