# At what rate would a bike going 16 Mph accelerate?

Topic: At what rate would a bike going 16 Mph accelerate?
June 26, 2019 / By Vanessa
Question: Okay, can anyone tell me at what rate a 24 inch bike accelerate at going 16 miles an hour. The bikes occupant is a 9 year old boy weighing 61 pounds with a height of 4.11 feet. If he were standing up, pushing all his weight on the pedals and front of the bike how much faster would he go if any at all? Or can somebody tell me how to figure this out or is it impossible as of right now. Also, when you hit an object dead on, do you jolt forward, or backward? What about if you hit it dead on but your moving at a slant? This is such a stupid question. No. Not homework. Physics was last year. Now it's biology and Earth and Space science. I'm just trying to create a realistic yet severe injury possibility and I assume the speed he is going is an important variable to the injury. I assure you. This is NOT homework.

"I'm just trying to create a realistic yet severe injury possibility" you are trying to kill a 9 year old.... ==== At what rate would a bike going 16 Mph accelerate? --why?

If your mother's main concern is safety then this will be very easy. You research how to safely operate a dirt bike, explain to her so she sees that you understand this. Talk to her about protective gear and illustrate for her that you understand her concern. Don't knock it by saying "Well a quad is more dangerous." That's not logic. If you want to win your mother over show her that you're responsible. Do your homework on bike safety. Don't just tell her you'll be safe, explain to her how you will be safe. She'll be more confident and more accepting of the whole idea if she trusts you on it.

Why 1971? That bikes as old as I am. Lol. My 14 year old son is looking at a 2008 quad. Save your money.

You may not have been paying attention during physics. If your bike hits something while you are riding, the bike stops, but you continue to move in the same direction until you also hit whatever the bike hit. If you hit something dead on you cant be at a slant with respect to the object. Review the concept of inertia. As for accelerating the bicycle, you don't have enough information to calculate acceleration. You don't know the gearing of the bike, and you don't know how much outside resistance there is. Pedaling a bike isn't as simple as pushing on the pedals. Serious cyclists spend countless hours perfecting their pedaling technique. In some cases that boy would actually slow down if he stood up to push on the pedals
