A daring ranch hand sitting on a tree limb wishes to drop vertically onto a horse galloping under the tree. The constant speed of the horse is 10.0 m/s, and the distance from the limb to the level of the saddle is 3.00 m. (a) What must be the horizontal distance between the saddle and limb when the ranch hand makes his move? (b) For what time interval is he in the air?
A celebrated Mark Twain story has motivated contestants in the Calaveras County Jumping Frog Jubilee, where frog jumps as long as 2.2 m have been recorded. If a frog jumps 2.2 m and the launch angle is 45, find (a) the frogs launch speed and (b) the time the frog spends in the air. Ignore air resistance.
Henrietta 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?
The velocity of a particle is given by v ={16t^2i +4t^3j + (5t +2)k} m/s, where t is in seconds. If the particle is at the origin when t = 0, determine the magnitude of the particle’s acceleration when t = 2 s. Also, what is the x, y, z coordinate position of the particle at this instant?
An object is moving along the x-axis. At t = 0 it is at x = 0. Its x-component of velocity vx as a function of time is given by vx(t)=αt−βt3, where α=α= 7.6 m/s2 and β= 4.4 m/s4. At what nonzero time tt is the object again at xx = 0?
An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?

On a one lane road, a person driving a car at v1 = 58 mi/h suddenly notices a truck 1.1 mi in front of him. That truck is moving in the same direction at v2 = 35 mi/h. In order to avoid a collision, the person has to reduce the speed of his car to v2 during time interval Δt. The smallest magnitude of acceleration required for the car to avoid a collision is a. During this problem, assume the direction of motion of the car is the positive direction. 1. Use the expressions you entered in parts (c) and (f) and enter an expression for a in terms of d, v1, and v2. a = ( v2 - v1 )/Δt Δt = ( 2 ) ( d )/( v1 - v2 ) 2. Calculate the value of a in meters per second squared.
Answer the ff: 1. A juggler throws a bowling pin straight up with an initialspeed of 8.20 m/s. How much time elapses until the bowling pinreturns to the juggler’s hand? 2. A car travels in the +x-direction on a straight and levelroad. For the first 4.00 s of its motion, the average velocity of thecar is vav-x = 6.25 m/s. How far does the car travel in 4.00 s?
From the top of a cliff, a person throws a stone straight downward. The initial speed of the stone just after leaving the person's hand is 8.1 m/s After 0.46 s, how far beneath the top of the cliff is the stone? (Give just the distance fallen, that is, a magnitude.) m
Taking north to be the positive y direction and east to be the positive x direction, a particle's position is given byr(t) = (20.2m/s)t^i+(5.15 m/s2)t2^jAt what time, in seconds, is the particle traveling exactly northeast?
