#

A ball is launched vertically from the ground with an initial speed of $$v = {{ params.v }}$$ $$\rm{m/s}$$.

Part 1#

What is the first time at which the ball is at a height of $${{ params.h }}$$ $$\rm{m}$$?

Please enter in a numeric value in $$\rm{s}$$.

Part 2#

Compute the velocity of the ball at $$t_1$$ (taking up to be positive).

Please enter in a numeric value in $$\rm{m/s}$$.

Part 3#

What is the second time at which the ball is at a height of $${{ params.h }}$$ $$\rm{m}$$?

• Please enter in a numeric value in $$\rm{s}$$.

Part 4#

Compute the velocity of the ball at $$t_2$$ (taking up to be positive).

Please enter in a numeric value in $$\rm{m/s}$$.
