Aprojectile fired up into the air at an angle has a range of 235 m and a flight time of 47 s.
a. what is the horizontal component of the projectiles velocity?
b. what is the maximum height of the projectile?
c. calculate viy for the projectile

Explanation:

Let , be the horizontal and vertical components of velocity.

Question a:

Horizontal component of velocity is the ratio of range and time of flight.

So,horizontal component of velocity is

So,

Question b:

Time of flight=

So,

Maximum height is given by

So,maximum height is

Question c:

The vertical velocity is already calculated in Question b.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
