The answer is not correct

If motor \( M \) exerts a force of \( F=\left(10 t^{2}+100\right) \mathrm{N} \) on the cable, where \( t \) is in seconds, determine the velocity of the \( 20-\mathrm{kg} \) crate when \( t=4 \mathrm{~s} \). The coefficients of static and kinetic friction between the crate and the plane are \( \mu_{s}=0.3 \) and \( \mu_{k}=0.25 \), respectively. The crate is initially at rest. Express your answer to three significant figures and include the appropriate units. X Incorrect; Try Again; 2 attempts remaining
