A ball is shot horizontally at 3 m/s and is in the air for 3 seconds. How far did it go?

Expert Solution

Projectile motion: When an object is thrown obliquely near the earth surface,it moves along curved path,this motion is called projectile motion.Here in this motion, is also an example of projectile motion with angle of inclination being 0° with the horizontal.Time of flight is the total time taken by an object to travel in air before coming to the ground.Since the ball is shot horitantally, therefore vertical component of velocity is zero.Accleration in horizontal axis is also zero.

A billiard ball is shot east at 2.80 m/s. A second, identical billiard ball is shot west at 1.20 m/s. The balls has a glancing collision, not a head-on-collision, deflecting the second ball by 90° and sending it north at 1.55 m/s. What is the angle that the velocity of the first ball makes after the collision, with respect to the east direction?

A ball of mass 500g is shot with an initial velocity of 10 m/s. the ball hits a pendulum bob (initially at rest) of mass of 2kg and the collision is perfectly elastic. a) find the velocity of the pendulum bob immediately after the collision. b) find the length of the pendulum if it comes to rest after turning by an angle of 30 degrees. - Part b is the one I am stuck on!!!

A ball of mass m is shot straight up into the air by a spring-loaded launcher. Initially, the spring is compressed by a distance D. After the spring is released, the ball has a velocity v out of the launcher and finally reaches a maximum height H. Ignoring air resistance, which of the following statements are true? True False If the spring constant is doubled, the ball will max out at height 8H True False The initial potential energy of the spring...

One billiard ball is shot east at 1.8 m/s . A second, identical billiard ball is shot west at 1.1 m/s . The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90∘ and sending it north at 1.49 m/s . a) What is the speed of the first ball after the collision? Express your answer to two significant figures and include the appropriate units. b) What is the direction of the first ball after...

A ball is kicked horizontally with 15 m/s initial speed from a cliff. The ball lands 75 m away from the base of the cliff (R = 75m). What is the height of the cliff? What is the hitting velocity (the velocity of the ball before it hits the ground)? What is the total time of flight?

7. A cue ball traveling horizontally at 2.5 m/s strikes a stationary 8-ball, causing the 8-ball to travel at a 30◦ angle with respect to the horizontal. If the two have the same mass, (a) What are the speeds of the cue and 8-ball post-collision? (b) Using your results, indicate what kind of collision occurred. You must back up your conclusion using your results.

One billiard ball is shot east at 1.9m/s . A second, identical billiard ball is shot west at 0.90m/s . The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90? and sending it north at 1.31m/s . 1.)What is the speed of the first ball after the collision? 2.)What is the direction of the first ball after the collision? Give the direction as an angle south of east.

An airplane flying in the air with a constant velocity of 240 m/s horizontally experiences a force due to gravity, directed downwards with a magnitude of 4×10^6 N, and a force generated by the engines, directed forwards with a magnitude of 3 × 10^6 N. a. In light of Newton’s first law, why must there be a third force acting on the airplane? Calculate the magnitude of this third force, and explain its physical origin. Draw this third force on...

When serving, a tennis player hits the ball horizontally. With a speed of 29.12 m/s. What minimum height, H (in m) from which the ball must be launched to just clear the 0.90 m high net about L = 17.65 m from the server. How far from the end of the service box (which is a distance of S = 6.80 m from the net) will the ball land if it just clears the net? Use the positive direction if...
