Answer:
Given-
u=20m/s , θ=30
o
, t=0.5s
Initial velocity-
u
=ucosθ
i
^
+usinθ
j
^
⟹
u
=u(cos30
o
i
^
+sin30
o
j
^
)
⟹
u
=20(
2
3
i
^
+
2
1
j
^
)
u
=10
3
i
^
+10
j
^
acceleration a=−g
j
^
=−10
j
^
since acceleration is acting downward
v
=
u
+
a
t
⟹
v
=(10

i
^
+10
j
^
)−(10
j
^
×0.5)
v
=10
3
i
^
+5
j
^
Change in velocity=Δ
v
=
v
−
u
=−5
j
^
Magnitude of change in velocity =5m/s
A short method is-
Δ
v
=acceleration×t=10×0.5=5m/s
Explanation:
bro my method is a bit different and question also but you can take from it I just need one brainliest
