Over 4 seconds, a car's momentum decreases by 1000 kg m/s how much force did it take to make this happen?
kotykmax [81]

Answer:

250N

Explanation:

Given parameters:

Time  = 4s

Momentum  = 1000kgm/s

Unknown:

Force  = ?

Solution:

To solve this problem, we use Newton's second law of motion;

      Ft  = Momentum

F is the force

t is the time

So;

          F x 4 = 1000kgm/s

          F  = 250N

Which statement best describes a device that has a high energy efficiency? Its ratio of energy absorbed to energy released is hi
Stels [109]

Answer:

It wastes little energy

Explanation:

  • The efficiency of a machine refers to the ratio of work output to the work input as a percentage.
  • The efficiency of most machines is less than 100% because some work is lost  due to friction and heat.
  • Therefore, a machine with high efficiency has less wastage of energy due to factors such as friction of the moving parts. Conversely, low efficiency means there is more wastage of energy.
