Answer to Question #279334 in Mechanics | Relativity for btch

Question

Superman throws a 2400-N boulder at an adversary. What

horizontal force must Superman apply to the boulder to give it a

horizontal acceleration of 12.0 m/s²?

Answer 1

$P = 240N \space\space\space\space a = 12\frac{m}{s^2}$

$F = ma = \frac{P}{g}a=\frac{240}{10}*12=288N$
