A 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? kN

An object is subject to a constant acceleration of 4.36 m/s? in the positive x direction. If it is initially at rest, what is its displacement in the x-direction at t = 6.99 s? %D

An object moving with uniform acceleration has a velocity of 10.0 cm/s in the positive x direction when its x coordinate is 3.06 cm. If its x coordinate 1.95 s later is -5.00 cm, what is its acceleration? cm/s²

A red object and a blue object are initially at rest at the same x-position. The object's then begin to accelerate in opposite directions as follows at t = O seconds; Red Object: a = 2.01 m/s? i Blue Object: a = -2.33 m/s?i At what time will the objects be separated by a distance of 107 m?

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/s²

An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 2.73 cm. If its x-coordinate 1.85 s later is −5.00 cm, what is its acceleration? cm/s2

A ball is thrown straight up with enough speed so that it is in the air for several seconds. Assume the positive direction is upwards.   Part A - What is the velocity of the ball when it reaches its highest point   Part B - What is its velocity 0.70s before it reaches its highest point?   Part C - What is the change in its velocity, v, during this 0.70s interval?   Part D - What is its velocity 0.70s after it reaches its highest point?   Part E - What is the change in velocity, v, during this 0.70s interval?   Part F - What is the change in velocity, v, during the 1.4s interval from 0.70s before the highest point is 0.70s after the highest point? (Caution: we are talking about velocity not speed)   Part G - What is the acceleration of the ball during any of these time interavals and at the moment the ball has zero velocity?
