Explanation:

Force = mass × acceleration

Mass = 900kg

Acceleration = velocity ÷ time

Velocity = 60km/hr = 60 × 1000 ÷ 3600

Velocity = 60000 ÷ 3600

Velocity = 16.67m/s

To get the time

Velocity = Distance ÷ time

16.67 = 50 ÷ time

Cross multiply

16.67 × time = 50

time = 50 ÷ 16.67

time = 3 seconds

Acceleration = 16.67 ÷ 3

Acceleration = 5.56m/s²

Therefore, Force = 900 × 5.56

Force = 5004 Newton

According to Newton's second law, how are acceleration and mass related? Directly or indirectly when force is constant?
Aliun [14]
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Electromagnetic induction is the creation of voltage or electromotive power because of an adjustment in the attractive field. Electromagnetic induction was found by Michael Faraday in the 1830s. Numerous electrical segments and sorts of gear work in light of the standard of electromagnetic induction .
