Now I KNOW you've heard this in class:
" F = M A "
"Force is equal to mass times acceleration. "
#26 TELLS you the mass and TELLS you the acceleration.
All you have to do is multiply them.
Do I have to do everything around here ?
Mass = 25 kg
Acceleration = 5 m/s²
Force = (25 kg) · (5 m/s²) = 125 kg-m/s² or 125 Newtons.
Whaddaya know ! ! ! There's a mistake on the sheet.
The correct answer is NOT printed there. It's 125 N.
