Answer:
5.31143691523 m/s²
Explanation:
m = Mass = 280 g
x = Displacement of spring = 21.7 cm
Time period
Angular velocity is given by
From Hooke's law
The acceleration due to gravity on the planet is 5.31143691523 m/s²
Yes, I have been able to satisfy my curiosity.
If there's no air resistance, then there are no horizontal forces on the ball.
With no horizontal force, there's no horizontal acceleration, so the horizontal speed never changes. From the time it's tossed until it hits the ground, its horizontal speed is the same 5 m/s. (B)
The answer is D. 3.0 m/s
force is mass × acceleration due to gravity
force = 6.0 N
mass = 2.0 kg
acceleration = ?
f = m×a
6 = 2×a
a = 6÷3
a = 3.0 m/s
