SUMMARY
The minimal force required to move a 20 kg block at a constant speed on a surface with a coefficient of friction of 0.30 is calculated to be 58.86 N. This value is derived using the formula for frictional force, which is the product of the coefficient of friction, mass, and gravitational acceleration (20 kg * 0.30 * 9.8 m/s²). According to Newton's 1st Law, the applied force must equal the frictional force for the block to maintain constant velocity, confirming that an applied force of 58.86 N is necessary.
