Question

A body is projected at an angle 30° with a horizontal and velocity 10m/s.Then its velocity after 1 second is ______(g= 10m's)​

Answer 1

Answer:

Speed=30m/s,t=1.5s,g=10m/s

2

So, the velocity along an x-axis

v

x

=ucosθ

30×cos30

0

=30×

2

3

=15

3

m/s

Again,

V

y

=usin30

0

−gt

30×

2

1

−gt

15−10t

Now After t=1.5s

v

x

=15

3

m/s

v

y

15−10×1.5=0

So 15

3

m/salong x-axis y making n angle zero.
