A body is projected upward at an angle of 30 degree with the horizontal at an initial speed of 200ms-1 in how many seconds will it reach the ground?how far from the point of projection will it strike?

Answer 1

init horiz speed (h) ... 200 m/s * cos(30º)

init vert speed (v) ... 200 m/s * sin(30º)

flight time (t) ... 2 v / g

impact distance (d) ... h * t

Answer 2

please answer this question and provide the diagram

Answer 3

Yes

Answer 4

Yes

Answer 5

Tita= 30°,U=200ms^-1
T=2Usintita/g
T=2(200)sin30/10
T=20secs.

Answer 6

I DONT UNDERSTAND

Answer 7

You know nothing

Answer 8

I want to be in this group

Answer 9

What response

Answer 10

For the first section,
Tita=30°
U=200ms^-1
g=10ms^-2
T=20seconds
As for the second one I don't get it

Answer 11

For the first section
Tita =30 degree
U=200m/s
g=10m/s^-2
T=2Usintita/g
T=2*200Sin30/10
T=20sec then R=U^2Sin2tita/g
200^2Sin60/10
34641.016/10
Therefore R=3464.1m
