A car traveling at 150 mi/hr strikes a wall and bounces backwards at 30 mi/hr. If the car is in contact with the wall for 0.1 seconds, what is the force that the car exerts on the driver?

Basis: n= 0 0 \sum 3*5^ 0 = 3 k= 0 3*(5 0+1-1) / 4 = 3 Assume: n \sum 3*5^k= 3*(5 n+1-1) / 4 k= 0 Prove: n+1 \sum 3*5 ^k= 3*(5 (n+1)-1) / 4 k= 0 ________________________________________ Proof: n+1...

I did these steps and I tried to complete the rest but I don't know some of the steps and what I is in the attached doc.

I need help to solve this problem Use induction to prove that, for n>=0: 3*5^0 + 3*5^1 + 3*5^2 + 3*5^3 + ...+ 3*5^n = 3*(5^(n+1)-1)/4 in other word n \sum 3*5 k= 3*(5 n+1-1) / 4 k= 0

1.the qustion is proof by contradiction is in the jpg file 2. the format of the solution is in the attachement doc.

Hi, I need help for 3 questions 1) Describe qualitatively the procedure for calibrating the force probe. 2) when determining the acceleration over a timeinterval, LoggerPro provides the following statistics : Average 0.107 Standard Deviation 0.120 Number of Points 54...

Hi, I'm new member and I would like to ask 2 questions: 1) Explain why an object too far from the motion detector will produce an incorrect distance reading? 2) Explain why we only consider one-dimesional motion when using a single motion detetor. Based on the definition of velocity...
