Answer:
In a two particle system, the center of mass lies on the center of the line joining the two particles.
The blank distance is your answer
Answer:
Vy = V0 sin 38 where Vy is the initial vertical velocity
The ball will accelerate downwards (until it lands)
Note the signs involved if Vy is positive then g must be negative
The acceleration is constant until the ball lands
t (upwards) = (0 - Vy) / -g = Vy / g final velocity = 0
t(downwards = (-Vy - 0) / -g = Vy / g final velocity = -Vy
time upwards = time downwards (conservation laws)
Answer:
distance cover is = 102.53 m
Explanation:
Given data:
speed of object is 17.1 m/s


from equation of motion we know that

where d_1 is distance covered in time t1
so
=


where d_2 is distance covered in time t2


distance cover is = 213.31 - 110.78 = 102.53 m
The answer is B friction force
