- While loading furniture into a truck, you push a 1.56 kg chair up a 14.7 degree ramp, with a horizontal force of 12.1 N. How long does it take to reach a speed of 4 m/s, starting from rest? The coefficient of kinetic friction chair - ramp is 0.345.An impala is an African antelope capable of a remarkable vertical leap. In one recorded leap, a 45 kg impala went into a deep crouch, pushed straight up for 0.21 s, and reached a height of 2.5 m above the ground. To achieve this vertical leap, with what force did the impala push down on the ground? What is the ratio of this force to the antelope’s weight?PHY 203 Introduction to Physics NAME:(17.1) A block of mass M = 20 kg rides on a frictionless horizontal plane surface whichwe choose to describe as the xy-plane. The z-direction is vertical, perpendicular to thexy-plane, with positive z pointing upward. At t = 0 , two constant applied forces,→F1 = 8 , 4 , 10N and →F2 = 12 , 6 , 10Nsuddenly begin to act. Take g = 10 m/s2for the weight force.(a) (i) Draw a free-body diagram, looking edge on to the plane, showing clearly the forceswhich act on the block in the vertical direction.(ii) Draw a free-body diagram, looking down on the plane, showing clearly the forceswhich act on the block in the horizontal direction.(b) Express each of the forces acting on the block in terms of its Cartesian components(in the directions specified by x, y, and z). [Hint: If you do not know the magnitude ofthe vector, but you do know its direction, then use a symbol – for the time being – for themagnitude.](c) Sum the forces to obtain the three components of…
- Tarzan, who weighs 820 N, swings from a cliff at the end of a 20.0 m vine that hangs from a high tree limb and initially makes an angle of 22.0 with the vertical. Assume that an x axis extends horizontally away from the cliff edge and a y axis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is 760 N. Just then, what are (a) the force on him from the vine in unit-vector notation and the net force on him (b) in unit-vector notation and as (c) a magnitude and (d) an angle relative to the positive direction of the x axis? What are the (e) magnitude and (f) angle of Tarzan’s acceleration just then?A 6.00 kg box sits at rest at the bottom of a ramp that is 8.00 mm long and is inclined at 30.0 degrees above the horizontal. The coefficient of kinetic friction is μk = 0.40, and the coefficient of static friction is μs = 0.43. What constant force F, applied parallel to the surface of the ramp, is required to push the box to the top of the ramp in a time of 6.00 s? Express your answer to four significant figures and include the appropriate units.Starting from rest, a 64.0 kg woman jumps down to the floor from a height of 0.610 m, and immediately jumps back up into the air.

(Round your answer to at least three significant figures.) d) To what height (in m) did she jump upon leaving the floor?
