Answer:
In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .
The letter D represents the wavelength
Earth's gravity pulls air as close to the surface as possible. As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.
Answer:28 m
Explanation:
Given
Direction is North of east i.e. with x axis
Also ball moved by 33 m
therefore its east component is 33cos58=17.48 m
Northward component
Answer:
Explanation:
Given
Initial velocity of ball
height of window
Using Equation of motion
where u=initial velocity
t=time
a=acceleration
As ball is already is at a height of 20 m so
(b)highest point is obtained at v=0
where
v=final velocity
u=initial velocity
a=acceleration
s=displacement
Highest Point will be
(c)Time taken when the ball hit the ground i.e. at Y=0
impact velocity
