A ball slows down while rolling up a slope. after $3\mathrm{.}0$ seconds have passed, the balls instantaneous velocity on its way up is $20$ cm$/$s$.$ after $8\mathrm{.}0$ seconds the ball comes to a stop $($v$=0$ cm$/$s$).$ if the ball acceleration was constant what was its speed at t$=5$ ?

Answer rating: 100% (QA)

To find the speed of the ball at t5 seconds we can use the kinematic equation v u at Where v final v... View the full answer
