Answer:
a)
b)
c)
d) Δs=4428ft
Explanation:
From the exercise we know the equation of position
a) To calculate the velocity we need to derivate the equation of position
So, v(0) is:
b) To find the two times where the particle stops A and B we need to solve the quadratic equation:
Solving for t
and
c)
d) Δs=4428ft-0ft=4428ft
Answer:
This ball will attain the same range at 60°.
Explanation:
Projectile motion: when an object is thrown in such a way that it form an angle with horizon, the force act on it that is the acceleration due gravity. This type of motion is known as projectile motion.
Range: The horizontal distance is covered by an object.
Range
u = initial velocity = 40 m/s
θ = 30°
g = gravity =9.8 m/s²
Next,
Range and u = 40 m/s
This ball will attain the same range at 60°.
