The gravitational force between the spheres is
where <em>G</em> = 6.674 x 10⁻¹¹ N m²/kg².
The weight of the lighter sphere is
where <em>g</em> = 9.80 m/s².
The ratio between the two forces is then
Answer:
(a). The distance is 49.79 m.
(b). The speed of the ball is 24.39 m/s.
Explanation:
Given that,
Speed = 20 m/s
Angle = 40°
Height = 22 m
Time = 3.25 sec
(a). We need to calculate the distance
Using formula of distance
Put the value into the formula
(b). We need to calculate the horizontal velocity
Using formula of velocity
Put the value into the formula
We need to calculate the vertical velocity
Using equation of motion
Put the value into the formula
Negative sign shows the opposite direction.
We need to calculate the speed of ball
Using formula of speed
Hence, (a). The distance is 49.79 m.
(b). The speed of the ball is 24.39 m/s.
