Solve the all parts of following question given below:
Question: You are traveling with a constant speed of 26 m/s.
Part A: What is this speed in units of mi/h?
Part B: How far do you travel (in m) in a time of 27 min? Does this value seem reasonable?
Part C: What can you say about the average speed during this time and the instantaneous speed at any instant during this time interval?
Please provide correct answer for above question.
A 1500 kg car traveling at a speed of 20 m/s skids to a halt on wet concrete where kinetic friction= 0.20. How far are the skid marks.
An object is oscilliating on a spring with a period of 4.60 s . At time t= 0.00 s the object has zero speed and is at x = 8.30 cm . What is the acceleration of the object at t= 2.50 s ?
Consider a non-ideal springthat exerts a force F(x)=-15.0 N/m x +3.00 N/m^2 x^2 , when it isdisplaced a distance x from its equilibrium length. Thedisplacement x is positive if the spring is stretched andnegative if the spring is compressed.
