sattari [20]

Answer:

0.6 pound.

Explanation:

From the question given above:

Julie applies 2.67 Newton (N) of force down onto the table.

Hence, we can obtain the force in pound applied by Julie on the table as follow:

Recall:

1 N = 0.225 pound

Therefore,

2.67 N = 2.67 × 0.225

2.67 N = 0.6 pound

Therefore, the force in pound applied by Julie on the table is 0.6 pound

At t = 0, object A is dropped from the roof of a building. At the same instant, object B is dropped from a window 10 m below the
dsp73

Answer:

Explanation:

Given two objects are dropped simultaneously

Object A is 10 m higher than object B therefore

Distance covered by object A is given by

y_a(t) is given by

y=ut+\frac{1}{2}at^2

where y=displacement

u=initial velocity

a=acceleration

t=time

y_a(t)=0+0.5gt^2--1

for object B

y_b(t)=0+0.5gt^2--2

Subtract 1 and 2 we get

y_a(t)-y_b(t)=0

i.e. they will travel equal distance in equal time and distance between them remain 10 m until object B hits the ground
