- A motorcycle starts from rest with an initial acceleration of 3.3 m/s?, and the acceleration then changes with distance s as shown. dv Determine the velocity v of the motorcycle when s = 250 m. At this point also determine the value of the derivative - ds 6.6 4.4 2.2 125 250 8, m Answers: V = i m/s dv ds a, m/s²A 70 kg man drops to a concrete patio from a window only 0.55 m above the patio. He neglects to bend his knees on landing, taking 2.0 cm to stop. (a) What is his average acceleration from when his feet first touch the patio to when he stops? m/s2 (b) What is the magnitude of the average stopping force? kNAn object of mass 5 kg is acted on by two forces F1 = 6 i N and F2 = 7 j N. What is the magnitude of the net acceleration? Give your answer in m/s2 to 2 sf. The magnitude must be a positive number.
- When referring to an object undergoing acceleration, we use the term, "gs" (geez), to refer to multiples of the free-fall acceleration value. True FalseCalculusii. Derive an expression for the maximum displacement possible for the block that will allow the block to still remain at rest. Express your answer in terms of MM, kk, μk, μs, and physical constants, as appropriate.
