  1. A strong, but inept, shot putter puts a shot straight up with a velocity of 8.0 m/s. If the point of release is 2.1 m above the ground, calculate how long it takes for the shot to hit the ground (you may assume that the shot putter gets out of the way)?

  2. A flea can jump to a height of 0.64 m. a) What is its initial speed as it leaves the ground? b) For how much time is the flea in the air?

Please tell me the equation and that you used and work out step by step :)))

A shot putter releases the shot some distance above the level ground with a velocity of 11.8 m/s, 52.8° above the horizontal. The shot hits the ground 2.10 s later. You can ignore air resistance. (Assume the horizontal direction of the shot and upward are positive.) (a) What are the components of the shot's acceleration while in flight? m/s2 (horizontal component) m/s2 (vertical component) (b) What are the components of the shot's velocity at the beginning of its trajectory? m/s...

A 3 kg cannonball is shot straight up from ground level at a velocity of 30 m/s. For the following questions, neglect air resistance and assume acceleration due to gravity is -10 m/s2. (a) Use the 1D equations of motion to find: i. The maximum height the cannonball reaches ii. The time it takes to reach this height iii. The time it takes to fall back to the ground iv. The speed with which it hits the ground

A small cannonball is shot straight up from the ground with a launch speed of 26.3 m/s. 2.00 seconds after the cannonball is launched, a ping pong ball is dropped from a height of 36.5 m. Both objects only move in the y-direction. 2a. Where (with respect to the ground) do the cannonball and the ping pong ball pass one another? 2b. How fast and in what direction are each of the balls traveling when they pass one another? 2c....

Suppose a 11.0 kg fireworks shell is shot into the air with an initial velocity of 68.0 m/s at an angle of 80.0° above the horizontal. At the highest point of its trajectory, a small explosive charge separates it into two pieces, neither of which ignite (two duds). One 9.00 kg piece falls straight down, having zero velocity just after the explosion. Neglect air resistance (a poor approximation, but do it anyway). (a) At what horizontal distance (in m) from...

1) A 85.0 kg football player leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 21.2 inches off the ground. He hits the ground 1.11 inches away from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball travelling? 2)You would like to shoot an orange in a tree with your...

Consider two projectiles that can be shot upward by spring guns. Object A is made of solid aluminum and has a mass of 50 grams. Object B is made of cast iron and has a mass of 200 grams. For this problem, you may take the gravitational field strength to be g = 10 N/kg. i. Masses A and B are both shot straight upward at the same time. Mass A is shot with a speed of 2 m/s and...
