Acceleration = ( final velocity - intial velocity ) / time

= (60-0)m/s / 3s
= 20 m/s2

Worth 20 points <br><br> Please answer showing the conversions
vladimir1956 [14]

Answer:

b) 18 m/s is the correct answer.

Explanation:

initial velocity(u) = 30m/s

acceleration(a) = -4m/s²

time(t) = 3 seconds

final velocity(v) = ?

using the formula,

a = (v-u)/t

or, -4 = (v-30)/3

or, -12 = v-30

or, v = -12+30

so, v = 18 m/s

In a very busy off-campus eatery one chef sends a 235-g broccoli-tomato-pickle-onion-mushroom pizza sliding down the counter fro
STALIN [3.7K]

Answer:

0.47922 kgm/s and will move right to left

Explanation:

m_1 = Mass of broccoli-tomato-pickle-onion-mushroom pizza = 235 g

m_2 = Mass of veggieburger-on-a-bun = 351 g

v_1 = Velocity of broccoli-tomato-pickle-onion-mushroom pizza = 1.65 m/s

v_2 = Velocty of veggieburger-on-a-bun = -2.47 m/s

Left to right is considered positive direction and the opposite is negative direction

Net momentum is

p=m_1v_1+m_2v_2\\\Rightarrow p=0.235\times 1.65+0.351\times -2.47\\\Rightarrow p=-0.47922\ kgm/s

The combined dish has a momentum of 0.47922 kgm/s and will move right to left

What structure help support plants
natka813 [3]
The cell structure that helps support plants is the cell wall. It provides a shell structure around the main cell of the plant and its layers so then it will have the adequate amount of strength that it needs. It's also one of the reasons why even non-woody plants such as herbs have the strength of support itself.
