The speed with which it leaves the barrel is 200 m/s and the mouth of the cannon is 2.00 m above ground level. Assume level ground. What are the horizontal and vertical components of the initial velocity of the cannon ball? Determine the velocity of the cannon ball at t = 6.0 s. What is the ball's velocity when it reaches its maximum height? How far down range (from the cannon mouth) does the ball land? (b) (d)

In the lab you explored how a lioness can catch a gazelle despite the fact that the lioness' top speed is slower than gazelle's, and gazelle has a distance head start during the chase. The graph below uses the same approximations you did in the lab and assumes that the lioness and the gazelle have constant accelerations until the they reach their top speeds. 30 Velocity, m/s 0 0 5 10 15 20 25 Time,s If lioness gave up an unsuccessful chase at the moment she reached her top speed, what was the minimal separation between the gazelle and the lioness at the start of the chase. Use the information given to you on the graph above for all parameters you need to answer the question. Assume that the gazelle had a head start in distance, but no head start in time. Gazelle's head start is greater than m

A street ball is dropped onto a hard floor from a height of 16.1 m and rebounds to a height of 1.34 m.  a. Calculate its acceleration during contact with the floor if that contact lasts 0.0900 ms. b. What distance did the ball compress during its collision with the floor, assuming the floor is absolutely rigid.

I may have the answer but I'm not sure

An unwary football player collides with a padded goalpost while running at a velocity of 7.7 m/s and comes to a full stop after compressing the padding and his body 0.36 m. a) What is his acceleration? Careful with the sign! b) How long does the collision last?

An object falls straight down 35.0 meters from the top of a building, landing on a metal box. The object crushes the box to a depth of 0.5 m.  Ignoring air resistance, calculate: Use coordinate system if needed. 1. The speed of the object just before it hits the box.  2. Assuming that the acceleration of the box is constant while crashing the box, calculate the time it takes the object to crush the box.

1. Jack drives a distance of 160 miles at an average speed of 35 miles/hr, followed by a distance of 190 miles at 75 miles/hr. What is his average speed over the 350-mile trip? Hint: Draw a labeled sketch of the trip. V avg miles per hour

1) A roller coaster's velocity at the top of a hill is 10 m/s. Four seconds later it reaches the bottom of the hill with a velocity of 36.2 m/s. What is the acceleration of the coaster? A 0or troxreli.
