Answer:
a)F=(208 i+156 j) kN
b)F+W=219 kN
Explanation:
Solution:
To determine the components of F
F=(260 kN).()
=(208 i+156 j) kN
F=(208 i+156 j) kN
b)weight W expressed in component and add into the
Force F.
W=-(8800 kg).(9.81 m/s^2)j
F+W=(208 i+[156-86.3]j) kN
F+W=
=219 kN
F+W=219 kN
Answer:
Acceleration will be
Explanation:
We have given that car is traveling with speed 34 miles per hour
So initial speed of the car u = 34 miles per hour
After 2 hour speed will be 84 miles per hour
So final speed V = 84 miles per hour
Time = 2 hour
From first equation of motion we know that
So acceleration
