Dec 04, 2016 · a. At what height above the ground do the balls collide? Your answer will be an algebraic expression in terms of h, v and g 0,. b. What is the maximum value of h for which a collision occurs before the first ball falls back to the ground? c. For what value of h does the collision occur at the instant when the first ball is at its highest point? 83. The Starship …
v = d/t. t = d / v. t for ball to move from thrower to catcher = (4.0 meters) / (5.0 m/s) t for ball to move from thrower to catcher = 0.800 seconds. The instant the ball is thrown, two motions occur - the ball moves forward towards the catcher and the thrower moves backwards towards the pond's edge. The ball reaches the catcher in 0.800 seconds.

A 60-unit impulse will change the momentum by 60 units, either increasing or decreasing it. If the impulse is in the direction of an object's motion, then it will increase the momentum. So now the object has 80 units (kg•m/s) of momentum. The object then encounters a resistive force of 6.0 N for 8.0 s.
Since this impulse is "resistive" in nature, it will decrease the object's momentum by 48 units. The object now has 32 units of momentum. The question asks for the object's velocity after encountering these two impulses. Since momentum is the product of mass and velocity, the velocity can be easily determined.
For a projectile launched horizontally, the horizontal component of a projectile's velocity is: Remains a non-zero constant. An athlete throws a ball with a velocity of 40 m/s at an angle if 20° above the horizontal.
A rock is thrown upwards at an angle of 40 degrees with respect to the horizontal. As the rock is rising in its trajectory, the vertical component of its velocity: Decreases. If the acceleration vector of an object is directed parallel to the velocity vector, then: The object is speeding up.
He uses a bow and arrow to launch the food to the monkey. If the person knows that the. monkey is going to drop from the tree at the same instant that the person launches the food, how should the person.
A monkey is sitting at the top of a tree 20 m high from the ground level. A person standing on the ground wants to feed the monkey. He uses a bow and arrow to launch the food to the monkey.

The opposite side of the crevasse is a height h lower , and is separated horizontally by a distance w . to cross the crevasse, the climber gets a running start and jumps in the horizontal direction. if the height of the crevasse increases but the width remains the same , then:
