Answer:

the distance covered by the body in 5th second =u+a(n- 1/2)=7+4(5- 1/2)

=7+4×9/2

=7+18

expeople1 [14]

Explanation:

v = u + a t

12 = 0 + 2a

a= 12/2

a=6 m/s2

v^2 - u ^2 = 2 as

12 ^2 - 0 ^2 = 2 * 6 * s

144 = 12 s

s = 144/12

s = 12 m

Elis [28]

Answer:

100 N

Explanation:

Given that,

Two forces whose resultant is 100newton are perpendicular to each other.

If one of them makes an angle of 60newton with the resultant.

$F_1=100\times \sin60=86.60\ N$

and

$F_2=100\times \cos60=50\ N$

The magnitude of force,

$F=\sqrt{F_1^2+F_2^2} \\\\F=\sqrt{86.6^2+50^2} \\\\F=99.99\ N$

F = 100 N

So, the magnitude of force is 100 N.

What is the name of the force that slows it down?.

Rus_ich [418]

Gravity pulls to the centre of the earth. A ship floats in water because the water pushing it up (upthrust) is equal to the force of gravity (weight) pulling it down. Friction also occurs when objects move through air. This is calledair resistance.
