Use the graph above to determine the change in speed of the object between 20 and 30 seconds?

allsm [11]

Answer:

6 m/s

Explanation:

To determine the change in speed of the object, we just need to determine its speed at t = 30 s and at t = 20 s, and then calculate the difference.

The speed at t = 30 is:

v = 6 m/s

While the speed at t = 20 s is:

u = 0

Therefore, the change in speed is:

$\Delta v = v-u=6-0 = 6 m/s$

A crate resting on a horizontal floor (\muμs = 0.61, \muμk = 0.3 ) has a horizontal force F = 49 Newtons applied to the right. T

Darya [45]

Answer:

a = 7.80 m/s²

Explanation:

given,

μs = 0.61

μk = 0.3

F = 49 N

we know,

F = μs m g

$m = \dfrac{F}{\mu_s\ g}$

$m = \dfrac{49}{0.61 \times 9.81}$

$m = 8.19\ kg$

now when the block start moving

$F - F_k = F_{net}$

$F - F_k = ma$

$a = \dfrac{F}{m}-\dfrac{F_k}{m}$

$a = \dfrac{F}{m}-\dfrac{\mu_k m g}{m}$

$a = \dfrac{88}{8.19}-0.3\times 9.8$

a = 7.80 m/s²
