3. A car, initially at rest, travels 48 m in 4 s along a straight line with constant
acceleration. Determine the magnitude of the acceleration of the car.
Answer and Solution:

Respuesta :

Magintude of Acceleration = 6 m/s -2

given - Initial velocity = 0

Time = 4s

Distance travelled = S = 48m

Acceleration = a = ?

Thus,

S= ut + 1/2 at2
The rate at which an object's speed changes, or the pace at which velocity changes, is known as acceleration. Newton's second law states that acceleration is inversely proportional to mass and directly proportional to the total sum of all forces acting on an item. It's simple math: if a thing is being pushed by a number of forces, you need to add them up (they may be acting in different directions), then divide the total force by the mass of the object.
