Answer:
Momentum = 1.534 kgm/s
Explanation:
Using the equations of motion, we can obtain the velocity of the ball as it hits the ground.
g = 9.8 m/s²
y = 12 m
u = initial velocity = 0 m/s, since the ball was released from rest
v = final velocity befor the ball hits the ground.
v² = u² + 2ay
v² = 0 + 2×9.8×12 = 235.2
v = 15.34 m/s
The momentum at any point is given as mass × velocity at that point
Mass = 100 g = 0.1 kg, velocity = 15.34 m/s
Momentum = 0.1 × 15.34 = 1.534 kgm/s
Answer:
C. 2.5 N
Explanation:
The sum of downwards moments equals sum of moments upwards
<u>Downwards moments </u>
Moments= Force*distance
= [10/100 * 2 ] +[20/100*4]
=[0.1*2] +[0.2*4]
=[0.2+0.8]
= 1.0 N
Equate this answer to upward force ;
1.0 N = 0.4 *U
1/0.4 =U
2.5 N =U
It’s atoms thank me later (give me brailiest)
Cleavage - the carbon atoms in graphite form sheets that could split apart easily in layers.
