Answer:
a = 1600 m / s²
Explanation:
For this exercise we use the kinematics relations,
v² = v₀² + 2 a x
where v₀ is the initial velocity of the bullet, which as part of rest is zero, for the distance (x) we can assume that the gases accelerate along the entire trajectory of the cannon x = 2m
a =
let's calculate
a =
a = 1600 m / s²
Answer:
Explanation:
Maximum height of the pumpkin,
Initial speed, v = 22 m/s
We need to find the angle with which the pumpkin is fired. the maximum height of the projectile is given by :
On rearranging the above equation, to find the angle as :
So, the angle with which the pumpkin is fired is 39.49 degrees. Hence, this is the required solution.
