Answer:
h = 81.63 m
Explanation:
Given that,
The speed of the car, v = 40 m/s
We need to find the height when the car comes to rest. We can use the conservation of energy to find it i.e.
So, it will reach to a height of 81.63 m and comes to rest.
Answer:
V=14.9 m/s
Explanation:
In order to solve this problem, we are going to use the formulas of parabolic motion.
The velocity X-component of the ball is given by:
The motion on the X axis is a constant velocity motion so:
The whole trajectory of the ball takes 1.48 seconds
We know that:
Knowing the X and Y components of the velocity, we can calculate its magnitude by:
