: At Time T The Position Of A Body Moving Along The S Axis Is S T3 21t2 120tm Find The Body S Acceleration Each Time The 1 (17.71 KiB) Viewed 34 times

At time t, the position of a body moving along the s-axis is s=t3−21t2+120tm. Find the body's acceleration each time the velocity is zero. A. a(10)=18 m/sec2,a(4)=−18 m/sec2 B. a(20)=120 m/sec2,a(8)=20 m/sec2 C. a(10)=0 m/sec2,a(4)=0 m/sec2 D. a(10)=−18 m/sec2,a(4)=18 m/sec2
