A blow gun next to a cliff shoot at a nearly 90 degrees up. Later it shoots at nearly 90 degrees down, missing the cliff. Which ball hits the ground below faster
Homework Answers
in the first case, initial velocity is in opposite direction to acceleration due to gravity, and in the second case, initial velocity is in the same direction as that of acceleration due to gravity. So the ball in the second case hits the ground faster.
Add Answer to:
A blow gun next to a cliff shoot at a nearly 90 degrees up.

A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air
A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...

9. A spring-loaded toy gun is used to shoot a ball of mass m-2.50 kg straight up in the air, as shown below. The spring has spring constant k-500 NI/m. If the spring is compressed a distance of 20.0 centimeters from its equilibrium position y-0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the gun. Assume that...

A ball is thrown up 90 feet in the air. it comes down, bounces, and then rises up to a height of 81 feet. Then it falls to its second bounce, and so on. Each time it falls, it bounces back to 90% of its previous height. (a) How high does the ball rise before the 30th bounce? (Please read the question carefully. If the question read “How high does the ball rise before the second bounce?” the answer would...

1. 2. A spring-loaded toy gun is used to shoot a ball of mass M straight up in the air. The ball is not attached to the spring. The ball is pushed down onto the spring so that the spring is compressed a distance S below its unstretched point. After release, the ball reaches a maximum height 35, measured from the unstretched position of the spring (see diagram below). Maximum Height Spring unstretched Spring compressed Mass released from west will...

A projectile is launched straight up at 58.5 m/s from a height of 90 m, at the edge of a sheer cliff. The projectile falls, just missing the cliff and hitting the ground below. (a) Find the maximum height of the projectile above the point of firing. m (b) Find the time it takes to hit the ground at the base of the cliff. s (c) Find its velocity at impact. m/s

What is faster, up or down? A ball of dough ?? = 1 kg is thrown vertically upwards from the surface of the Earth, with a positive initial velocity ??0 = 20 m / s. Suppose the forces acting on the ball are gravity and a retarder of air resistance, with opposite direction to that of the movement. 2._ If the retarding force is proportional to the instantaneous velocity, use the second law of Newton to determine an equation that...
