Question

? What is the magnitude of force required to accelerate a car of mass 1.7 × 103 kilograms by 4.75 meters/second2

Answer 1

f=ma

f=175.1*4.75m/s

f= 831.725N

Answer 2

Answer:

F=8075 N

Explanation:

The second newton's law state the relation between the force and the acceleration by the formula:

F=m.a

Where F is the force, m is the mass and a is the acceleration.

It is known that the mass of this car is 1.7x10^3 kg and its acceleration is 4.75 m/s^2. Replacing in the formula:

F=(1.7x10^3 kg)(4.75 m/s^2)

F=8075 N
