- A projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one-sixth as large. How does the range of the projectile on the Moon compare with that of the projectile on the Earth? (a) It is one-sixth as large, (b) It is the same, (c) It is V5 limes larger, (d) It is 6 times larger, (e) It is 6limes larger.arrow_forwardHobbyists build a compressed air powered cannon which is able to launch a pumpkin a horizontal distance of 2700 ft. Assuming no air resistance, and assuming the pumpkin is launched at ground level, what is the minimum initial speed of the pumpkin (just as it leaves the cannon) that is needed for it to reach this distance, in m/s? 294 X m/sarrow_forwardHenrietta is going off to her physics class, jogging down the sidewalk at a speed of 3.45 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 36.4 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 7.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance. With what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground? Where is Henrietta when she catches the bagels?arrow_forward
- 2. An archer standing on the back of a pickup truck moving at 28 m/s fires an arrow straight up at a duck flying directly overhead. He misses the duck. The arrow was fired with an initial vertical velocity of 49 m/s relative to the truck. (a) For how many seconds will the arrow be in the air? (b) How far will the truck travel while the arrow is in the air? (c) Where, in relation to the archer, will the arrow come down? (Ignore air friction.) Will the archer have to "duck"? Explain.arrow_forwardA person on the top of a roof of a building (100 m) drops a ball. After 2s passed, a person who stands at the base of the same building throws a separate ball in the upward direction with a speed of 20 m/s. Assumes the two balls are traveling on the same vertical path. Will the two balls collide with each other? If so, what are their velocities as they collide with each other?arrow_forward71. ssm Multiple-Concept Example 4 provides useful background for this problem. A diver runs horizontally with a speed of 1.20 m/s off a platform that is 10.0 m above the water. What is his speed just before striking the water?arrow_forward
- 1. A ball is thrown into the air with an initial x velocity of 15 m/s and an initial y velocity 10 m/s from an initial height of 20 m. a) What is the maximum height of the ball? How long does it take the ball to reach its maximum height? b) What is the range of the ball?arrow_forwardHenrietta is going off to her physics class, jogging down the sidewalk at a speed of 4.10 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 43.4 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 5.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance Part A With what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground?

Position of a particle is defined by Cartesian coordinates x(t) = 4+ Br", y(t)=24t , where A = const and B= const. Write vectors of velocity and acceleration of the particle, find magnitude of these vectors.arrow_forward
- a catapult launches a test rocket upward from well giving it a speed of 50 m/s at ground level. the engines then fire so that the rocket accelerated at 5 m/s^2 until it reaches an altitude of 750 m at which point it gos into free fall. what is the maximum altitde of the rocket?arrow_forwardAn inflatable raft (unoccupied) floats down a river at an approximately constant speed of 5.2 m/s. A child on a bridge, 82 m above the river, sees the raft in the river below and attempts to drop a small stone onto the raft. The child releases the stone from rest. In order for the stone to hit the raft, what must be the horizontal distance between the raft and the bridge when the child releases the stone? marrow_forwardHenrietta is going off to her physics class, jogging down the sidewalk at a speed of 3.30 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 52.5 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 9.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance. I. With what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground? (Express your answer in meters per second.) II.
