Extreme-sports enthusiasts have been known to jump off the top of El Capitan, a sheer granite cliff of height 910 min Yosemite National Park. Assume a jumper runs horizontally off the top of El Capitan with speed 4.0 m/s and enjoys a free fall until she is h= 190 mabove the valley floor, at which time she opens her parachute. Part A How long is the jumper in free fall? Ignore air resistance. Express your answer using two significant figures and include the appropriate units. Part B It is important to be as far away from the cliff as possible before opening the parachute. How far from the cliff is this jumper when she opens her chute? Express your answer using two significant figures and include the appropriate units.

Extreme-sports enthusiasts have been known to jump off the top of El Capitan, a sheer granite cliff of height 910 mm in Yosemite National Park. Assume a jumper runs horizontally off the top of El Capitan with speed 5.0 m/sm/s and enjoys a freefall until she is 150 mm above the valley floor, at which time she opens her parachute. Part A How long is the jumper in freefall? Ignore air resistance. Part B It is important to be as far away from the cliff as possible before opening the parachute. How far from the cliff is this jumper when she opens her chute? Express your answer using two significant figures.
The record distance in the sport of throwing cowpats is 81.1 m. This record toss was set by Steve Urner of the United States in 1981. Assuming the initial launch angle was 45° and neglecting air resistance, determine (a) the initialspeed of the projectile and (b) the total time interval the projectile was in flight. (c) How would the answers change if the range were the same but the launch angle were greater than 45°? Explain.
In a cartoon program, Peter tosses his baby, Stewie, up into the air to keep the child entertained. Stewie reaches a maximum height of 0.613 m above the release point. Suppose the positive y axis points upward. (a) With what initial velocity was Stewie thrown? (Express your answer in vector form.) (b) How much time did it take Stewie to reach the peak height?
(a) If a flea can jump straight up to a height of 0.440 m, what is its initial speed as it leaves the ground? (b) How long is it in the air? Note: Round off your answers in the nearest hundredth.
A player throws a ball [You can assume g ≃10 m/s2; Ignore air resistance. 1ft=0.305m] a) At what initial speed must the robot throw the ball to make the shot, given the sketch above? (b) How far in the horizontal direction from the point of release is the ball at its maximum height? (c) What is the velocity of the ball (magnitude and direction) as it goes through the hoop?
(a) A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 32° ramp at a speed of 40.0 m/s (144 km/h) . How many buses can he clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 20.0 m long? (b) Discuss what your answer implies about the margin of error in this act—that is, consider how much greater the range is than the horizontal distance he must travel to miss the end of the last bus. (Neglect air resistance.)
(a) What are the coordinates of the initial position of the stone? x0 = m y0 = m (b) What are the components of the initial velocity? v0x = m/s v0y = m/s (c) Write the equations for the x- and y-components of the velocity of the stone with time. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not include units in your answer.) vx = vy =
A baseball leaves a pitcher’s hand horizontally at a speed of 161 km/h.The distance to the batter is 18.3 m. (a) How long does the ball take to travel the first half of that distance? (b) The second half? (c) How far does the ball fall freely during the first half? (d) During the second half? (e)Why aren’t the quantities in (c) and (d) equal?
A rugby player passes the ball 7.00 m across the field, where it is caught at the same height as it left his hand. (a) At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? (b) What other angle gives the same range, and why would it not be used? (c) How long did this pass take?
