Projectile of ball launched to a specific height#

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

Part 1#

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

Answer Section#

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

Part 2#

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

Answer Section#

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

Part 3#

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

Answer Section#

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

Part 4#

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

Answer Section#

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