Jerry the mouse is running along a straight desert road at a constant velocity of 18 m/s. If a certain Tom cat wants to capture Jerry using a net dropped from an bridge that is 15m high, how much time before Jerry is under the bridge, should Tom drop the net? s How far away from the bridge is Jerry when Tom drops the net? m

a) t = 1.75 s

b) x = 31.5 m

Explanation:

a) The time at which Tom should drop the net can be found using the following equation:

Where:

: is the final height = 0

y₀: is the initial height = 15 m

g: is the gravity = 9.81 m/s²

: is the initial vertical velocity of the net = 0 (it is dropped from rest)

Hence, Tom should drop the net at 1.75 s before Jerry is under the bridge.

b) We can find the distance at which is Jerry when Tom drops the net as follows:

Then, Jerry is at 31.5 meters from the bridge when Jerry drops the net.

I hope it helps you!                                                                    

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.
