Susan asks…Physics - Acceleration Problem?I wanted to check if I did this problem right.
A ball is thrown straight up with an initial speed of 30 m/s. Use g(gravity) = -10 m/s^2.
a. How long will it take the ball to reach the top of its trajectory?
I said 3 seconds because every second gravity acts on the ball so after 3 seconds 3x-10=-30 cancels out the initial speed, then it will begin descending.
b.What will the ball's acceleration be at the top of its trajectory (assume no air
