Suppose you throw a rock nearly straight up at a coconut in a palm tree, and the rock misses on the way up but hits the coconut on the way down. Neglecting air resistance, how does the speed of the rock when it hits the coconut on the way down compare with what it would have been if it had hit the coconut on the way up? Is it more likely to dislodge the coconut on the way up or down? Explain,
Towns A and B in Figure P4.64 are 80.0 km apart. A couple arranges to drive from town A and meet a couple driving from town B at the lake, L. The two couples leave simultaneously and drive for 2.50 h in the directions shown. Car 1 has a speed of 90.0 km/h. If the cars arrive simultaneously at the lake, what is the speed of car 2?
While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.61 m/s. The stone subsequently falls to the ground, which is 17.3 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. A) Impact speed: _________________________ m/s B) How much time is the stone in the air? elapsed time: ____________ s
1e. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. How long after being released does the stone strike the beach below the cliff? (in seconds)
Nate throws a ball straight up to Kayla, who is standing on a balcony 3.8 m above Nate. When she catches it, the ball is still moving upward at a speed of 2.8 m/s. With what initial speed did Nate throw the ball?A. 7.0 m/s B. 12.3 m/sC. 9.1 m/s D. 10.6 m/s
Two students are on a balcony 18.6 m above the street. One student throws a ball (ball 1) vertically downward at 13.1 m/s; at the same instant, the other student throws a ball (ball 2) vertically upward at the same speed. The second ball just misses the balcony on the way down. (a) What is the difference in the two ball's time in the air? (b) What is the velocity of each ball as it strikes the ground?
While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 7.39 m/s. The stone subsequently falls to the ground, which is 19.1 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. impact speed: How much time is the stone in the air? elapsed time:
A catapult above an 8m hill launched a ball with 15 m/s initial velocity and hit a moving cart. If the cart was moving 5 m/s towards the hill, how many meters away was the cart from the hill at the moment the ball was launched (initial position of the cart)? a. 18 b. 32 c. 35 d. 15
A baseball player throws a baseball straight up into the air, in the following way: Starting from a height of 1.0 m above the ground, he accelerates the ball vertically with 30. m/s2 for 0.25 s, then the ball leaves his hand and flies straight up in free fall. Let’s ignore the air resistance. Draw a carefully labeled sketch of the situation. Calculate the velocity of the ball as it leaves the player’s hand. How high does the ball go relative to its initial position (yo=1.0 m)? Shows all work please.
A person can survive a feet-first impact at a speed of about 12 m/s (27 mi/h) on concrete; 15 m/s (34 mi/h) on soil; and 34 m/s (76 mi/h) on water. Why the different values for different surfaces?
A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward. After the rocket's engine turns off at a height of h=1.04kmℎ=1.04km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per squared second, during the period from engine shutoff until it returns to the ground?
You throw a stone from the ground and it lands on a high wall of height h with an initial velocity of 21.0 i + 36.4 j. The stone hits the top of the wall 5.50 s after you throw it. Find (a) The height h of the wall (b) The speed of the stone right before it hits the wall (c) The maximum height H reached above the ground
