Answer:
The correct answer will be "1477.84 N".
Explanation:
Given that,
Mass,
m = 1.6 mg
or,
= 1600 kg
Initial velocity,
u = 72 km/h
=
=
Final velocity,
v = 18 km/h
=
=
Covered distance,
s = 250 m
By using the below relation, we get
⇒
On putting the values, we get
⇒
⇒ (shows the deceleration)
Slope will be given as 1 in 25, then
⇒
hence,
As we know,
⇒
or,
⇒
⇒
On substituting all the values, we get
⇒
⇒
Answer:
The resulting strain is .
Explanation:
A specimen of copper having a rectangular cross section 15.2 mm × 19.1 mm
Force, F = 44,500 N
Th elastic modulus of Cu to be 110 GPa
The resulting strain is given by the formula as follows :
E is elastic modulus of Cu is are of cross section
So, the resulting strain is .
