Question

A projectile launched upwards from ground has a range of 180m and its timeof flight is 10 s.The velocity(in m/s) after 5s from start is (angle of projection with horizontal is theta)?

Answer 1

this time , you have to show some your working first ;)

Answer 2

do you know your formulas?

Answer 3

s

Answer 4

?

Answer 5

R=u^2sin2theta/g

Answer 6

T=2usintheta/g

Answer 7

Using the time of flight and range find out angle of projection.
Can you tell at which position the object will be in 5 sec?
