A car travels with an average speed of 22 m/s.what is this speed in km/s
2 answers:
Answer:
22 m/s = 79.2 km/h
Explanation:
Given that,
The average speed of the car is 22 m/s. Here, we need to convert the speed to km/h. Firstly, we will see the following conversions as :
1 kilometres = 1000 meters
1 hour = 3600 seconds
To convert m/s to km/h we must use these coversions.
After solving the above expression, we get
22 m/s = 79.2 km/h
So, the car travel with a speed of 79.2 km/h. Hence, this is the required solution.

Answer:
Initial velocity = 10 m/s
θ = 60°
This is the case of projectile motion
So the horizontal component of velocity 10 m/s = 10 cosθ
u = 10 cosθ
u = 10 cos 60°
u=5 m/s
x= 5 m
So in the horizontal direction
x = u .t
5 = 5 .t
t = 1 sec The vertical component of velocity 10 m/s = 10 sinθ
Vo= 10 sinθ
Vo= 10 sin 60°
Vo = 8.66 m/s
h=3.75 m
So height of robot = 3.75 - 0.75 m
height of robot =3 m
