The truck will require force to stop:
Force equals Mass x Acceleration (F = m * a)
Both vehicles will need to decelerate by 55 miles per hour, so the one with a greater mass, m, will require more force to stop. The truck has a mass of 4000 kg, which is greater than the car's
Answer:
Difference is given below.
Explanation:
The main difference between beneficial and harmful friction is that beneficial friction is necessary for performing different activities while on the other hand, harmful effect of friction is destroy different parts of products and machines. examples of beneficial friction are walking, holding things, rubbing hands to produce heat, running etc whereas examples of harmful friction are destruction of sole, slipping, tearing of machine's part, Wet roads and Mudslides etc.
