Would a 200lb rubberband ball Damage the road if dropped from 150ft?

Question

I own a huge 200lb rubberband ball. I am going to drop it off a bridge thats around 150ft high onto an old road. WILL IT CRACK OR PUT A CRATER IN THE ROAD? Even though the ball is made of rubber it is extremely dense. what do you think?
Thanks

Answer 1

m = 200/2.2 = 91 kg
x = 150 ft = 46 meters

t = (2x/g)^2 = (92/9.8)^2 = 3.1 sec (time to impact)
Vf = gt = 3.1 * 9.8 - 30 m/sec (velocity at impact)
KE = 0.5mv^2 = 0.5 * 91 * 30^2 = 41 kJ (kinetic energy of impact)

Now, if you know how much energy will be absorbed by the ground and how much is retained in the rebound, then what the compressive strength is of the road, then you be cooking with gas.

My guess is very little energy will be transferred to the road compared to retained by the ball on the rebound and that the compressive strength of the road material is relatively high.

Go for it.

Answer 2

ANything weighing 100 punds will damage a road from 50 metres ie 150 ft

Answer 3

No way will a 200 lb. rubber band ball damage an old road's surface dropped from 150 feet. But I sure would like to see that sucker bounce.

Answer 4

there are various techniques- one million- tie a knot out of a super fat rubber band and shop tying the ends jointly until it is like a sprint nugget and paintings from there 2- use an previous shaped steel jack (the type you %. up once you bounce the rubber ball) to wrap the 1st bands around 3- use a small rubber ball. sturdy success!

Answer 5

ive seen something similiar on t.v. except it was dropped from an airplane and the rubberbands just snapped on impact

Answer 6

make sure you get that on tape and put it on ebaums or youtube so we can all see what happens.
