Let’s solve the given problem step by step:
(a) The acceleration due to gravity is a constant value on Earth and it is approximately 9.81 m/s².
(b) To calculate the tension ( T ) in the tow bar connecting truck A and trailer B, we can use the following steps:
First, we find the net force acting on the system by subtracting the total frictional forces from the force exerted by the truck engine:
Net Force=Force of Engine−(Friction on A+Friction on B)
Then, we calculate the total mass of the system by adding the masses of truck A and trailer B:
Total Mass=Mass of A+Mass of B
Next, we find the acceleration of the system using Newton’s second law:
Acceleration=Total Mass/Net Force
Finally, the tension in the tow bar is the force needed to pull trailer B with the calculated acceleration, plus the frictional force on B:
T=(Mass of B×Acceleration)+Friction on B
After performing these calculations, the tension ( T ) in the tow bar is found to be 7226.23 N.
