Answer:
Maximum height, h = 1.74 meters
Explanation:
It is given that,
A potato is shot out of the cylinder. It is a case of projectile motion. The potato makes an angle of 17 degrees above the horizontal.
Initial speed with which the potato is shot out, u = 20 m/s
We have to find the maximum height of the potato. The maximum height of a projectile (h) is given by the following formula as :

Where
= angle between the projectile and the surface
g = acceleration due to gravity

h = 1.74 m
or h = 1.74 meters
Hence, this is the required solution.
We will first record its mass and then its volume by measuring its dimensions
then divide mass by volume and will get density of regular solid
