The answer is below
Explanation:
a) The location ӯ of the center of mass G of the pendulum is given as:
b) the mass moment of inertia about z axis passing the rotation center O is:
c) The mass moment of inertia about z axis passing the rotation center O is:
As we know that range of the projectile motion is given by
here we know that range will be same for two different angles
so here we can say the two angle must be complementary angles
so the two angles must be
so it is given that one of the projection angle is 75 degree
so other angle for same range must be 90 - 75 = 15 degree
so other projection angle must be 15 degree
Answer:
7.04 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 0
s = Displacement on Earth = 1.2 m
a = Acceleration due to gravity on Moon = 1.67 m/s²
a = Acceleration due to gravity Earth= 9.81 m/s²
Accelration going up is considered as negetive
Initial Velocity of the ball
Assuming that the ball is thrown with the same velocity on the Moon, displacement of the ball is
The displacement of the ball on the moon is 7.04 m
