Acannonball is tired with an initial speed of 40m/s and a launch angle of 30degrees from a cliff that is 25m tall. a. what is the flight time of the cannonball b. how far away does the cannonball land c. using two graphs, plot the horizontal speed of the projectile versus time and the vertical speed of the projectile versus time (from the initial launch of the projectile to the instant i strikes the ground).

Part a)

Part b)

Explanation:

Initial speed of the launch is given as

angle = 30 degree

Now the two components of the velocity

similarly we have

Part a)

Now to find the time of flight we will have

Part b)

Distance at which the ball will land is given as

Part c)

Since x direction there is no acceleration so it will move with uniform speed while in y direction it will accelerate due to gravity

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get
