A ball is thrown straight up into the air from the ground with initial velocity v0= 4 m/s, it reaches its apex and falls back down. Neglecting air resistance, how long does it take the ball to return to the ground?

Q 6.28: As a 3.3-N apple falls from a 3.5-m tree under the influence of gravity, a constant air drag force of 0.22 N acts on the apple. Determine the work done on the apple by the conservative force in this situation.

An airplane flies horizontally at a speed of 482 km/h and drops a crate that falls to the horizontal ground below. Neglect air resistance. a) If the altitude of the plane was 582 m, then how far, horizontally in meters, did the crate move as it fell to the ground? b) what was the speed of the crate, in m/s, just before it hit the ground?

A 170 gram ball is dropped from rest off of a cliff. the ball then drops straight down to the ground, 19m below. if the speed of the ball just before it hits the ground is 8 m/s, how much work is done to the ball by the fore of air resistance as it falls?

On a warm spring day, the last icicle on the roof falls to the ground. The icicle has a mass of 0.4 kg, and starts at a rest and a height of 6.9 m above the ground. A. What is the magnitude of the velocity of the icicle just before it hits the ground? Ignore air resistance. m/s B. Now, we will model the icicle hitting the ground as an object falling onto and then compressing a spring. (The small...

A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...

Maria throws an apple vertically upward from a height of 1.3 m with an initial velocity of +2.9 m/s. Will the apple reach a friend in a tree house 7.0 m above the ground? The acceleration due to gravity is 9.81 m/s2. 1. No, the apple will reach 5.27136 m below the tree house 2. Yes, the apple will reach 5.27136 m above the tree house 3. No, the apple will reach 1.43117 m below the tree house 4. No,...

A rocket is fired at an initial speed v0 = 141.0 m/s from ground level, at an angle θ = 33 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component of the initial velocity (in m/s) (c)...
