Answer
given,
mass of satellite = 545 Kg
R = 6.4 x 10⁶ m
H = 2 x 6.4 x 10⁶ m
Mass of earth = 5.972 x 10²⁴ Kg
height above earth is equal to earth's mean radius
a) satellite's orbital velocity
centripetal force acting on satellite =
gravitational force =
equating both the above equation
v = 5578.5 m/s
b)
T = 14416.92 s
T = 4 hr
c) gravitational force acting
F = 5202 N
Answer:
Explanation:
Given data
Initial speed vi=0 m/s
Final speed vf=19.0 m/s
Δy=1.10 m
Mass of ball m=0.150 kg
To find
Force
Solution
First we need to find acceleration of the ball.So we can apply:
vf²=vi²+2aΔy
vf²=0+2aΔy
Because we get the acceleration of the ball.We can now find the force the players exerts on the ball by using Newtons second law
∑F=F.player -mg=ma
The distance traveled per unit time is called speed.
