Apotato is shot out of cylinder at an angle of 17 degrees above the horizontal with an initial speed of 20 m/s. what is its maximum height?

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.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
