The cart with the fastest acceleration is 5 kg cart because its mass is the smallest.
The given parameters;
applied force, F = 90 Nmass of cart: 5kg, 6kg, 8 kg, 9 kg
According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
F = ma
The acceleration of the 5 kg cart is calculated as follows;
The acceleration of the 6 kg cart is calculated as follows;
The acceleration of the 8 kg cart is calculated as follows;
The acceleration of the 9 kg cart is calculated as follows;
Thus, the cart with the fastest acceleration is 5 kg cart because its mass is the smallest.
