A 0.500-kg potato is fired at an angle of 80.0° above the horizontal from a PVC pipe used as a “potato gun” and reaches a height of 110.0 m. (a) Neglecting air resistance, calculate the potato’s velocity when it leaves the gun. (b) The gun itself is a tube 0.450 m long. Calculate the average acceleration of the potato in the tube as it goes from zero to the velocity found in (a). (c) What is the average force on the potato in the gun? Express your answer in newtons and as a ratio to the weight of the potato.

Based on a grade 11 physics student, answer the following question: A poké-ball rolls off Ash’s table with a velocity of 1.93 m/s [horizontally].  The tabletop is 76.5 cm above the floor.  If air resistance is negligible, determine  how long the poké-ball is airborne the horizontal range (distance) the velocity at impact

A projectile is fired horizontally into a resisting medium with a velocity vo = 2.6 m/s and the resulting deceleration is equal to cv. where c = 0.038 m ³s 4, and v is the velocity within the medium. Find the velocity v of the projectile at time t = 4.7 s after penetration. Answer: vi m/s

An archer shoots an arrow at a 78.0 m distant target, the bull's-eye of which is at same height as the release height of the arrow. (a) At what angle must the arrow be released to hit the bull's-eye if its initial speed is 33.0 m/s? (Although neglected here, the atmosphere provides significant lift to real arrows.) (b) There is a large tree halfway between the archer and the target with an overhanging branch 3.50 m above the release height of the arrow. Will the arrow go over or under the branch?

A box has a mass of 67 kg, a force of 91 N is applied to it at an angle of 45º, an object moves on a surface of 29 m with a coefficient of kinetic friction = 0.04 and where its initial velocity is equal to 13 meters/sec. in said path: Determine the magnitude of the normal (n).

A projectile is fired at ?0=394.0 m/s at an angle of ?=72.0∘, with respect to the horizontal. Assume that air friction will shorten the range by 33.1%. How far will the projectile travel in the horizontal direction, ??

A very bored 318 kg bear decides to jump across a stream. The stream is 6 m wide and the east bank of the stream is 1m higher than the west bank (where the bear starts). The bear can jump with an initial velocity vi = (4m/s, 4m/s , and decides to start from 3m in the air, halfway up a sturdy tree. If the origin is at the bear's foot (up in the tree), write an equation describing the coordinate of the bear while it is in the air. Use the following table as a reference. Note that it may not be necessary to use every variable.

A projectile is fired horizontally into a resisting medium with a velocity vo = 3.2 m/s and the resulting deceleration is equal to cv5, where c = 0.022 m-4s-³, and v is the velocity within the medium. Find the velocity v of the projectile at time t = 5.7 s after penetration. Answer: v= i jak w m/s

An archer shoots an arrow at a 78.0 m distant target, the bull's-eye of which is at same height as the release height of the arrow. (a) At what angle must the arrow be released to hit the bull's-eye if its initial speed is 37.0 m/s? (Although neglected here, the atmosphere provides significant lift to real arrows.) °(b) There is a large tree halfway between the archer and the target with an overhanging branch 3.50 m above the release height of the arrow. Will the arrow go over or under the branch? over under

A pumpkin of mass 5 kg shot out of a student-made cannon under air pressure at an elevation angle of 45° fell at a distance of 142 m from the cannon. The students used light beams and photocells to measure the initial velocity of 54 m/s. If the air resistive force was F = -kmv, what was the value of k?
