<span>F= ma force is directed on the working surface so 40 = m x 2 hence
m must be 20 units needed are probably kg</span>
Answer:
If the force remains the same, the acceleration would decrease
Explanation:
According to Newton's second law, the acceleration of an object is given by

where
F is the force applied to the object
m is the mass of the object
As we see from the formula, the acceleration a is inversely proportional to the mass, m. Therefore, if the force F remains constant, this means that if the mass of the skateboarder increases, then the acceleration will decrease.
Heat exhaustion is usually accompanied by a fever no higher than 104 degrees Fahrenheit, excessive thirst, nausea, fainting, cool and clammy skin, weakness, muscle aches, heavy sweating, slow heartbeat and dizziness. Heatstroke may develop following heat exhaustion if the condition is not treated.
