Question

if a body is thrown with a speed of 19.6 M per second making an angle of 30° with the horizontal then time of flight is

Answer 1

Time taken by an object to cover a parabolic path is given by this simple formula

T=2usinx/g

Where T is time period

u is initial velocity

x is the angle made by horizontal

g is gravity

SUBSTITUTING ALL THE VALUES WE GET:

2*19.6*sin 30/9.8

=2*19.6*1/(2*9.8)

=2 seconds

Hence the total time taken is 2 seconds.

Answer 2

Answer:

Explanation:

Time taken by an object to cover a parabolic path is given by

T=2usinx/g

Where

• T is time period
• u is initial velocity
• x is the angle made by horizontal
• g is gravity

By substituting the given values

(2*19.6*sin 30)/9.8

=(2*19.6*1)/(2*9.8)

=2 seconds

Hence the total time taken is 2 seconds
