From Newton’s 2nd law of motion
F=ma
= 2*4
=8N
8N should be the answer
Answer:
(1) Support
(2) Tension
(3) Reaction
The constraint forces are forces that occur in pairs such that the net force (effect) is zero
The details of the constraint forces are;
(1) The support force at the top of the swing acting upwards
(2) The tension in the swing rope acting upwards
(3) The (normal) reaction between the legs of the swing frame and the ground
Explanation:
The normal reaction is the force equal in magnitude and opposite in direction to the total weight force the swing and the person on the swing posses due to gravitational attraction which prevents the downward or sideways motion of the entire swing
Answer:
bring each tube close to the plastic ball and note any movement of the ball
Explanation:
study island
just took the test!!!!!
Explanation:
Momentum is conserved.
a) In the first scenario, Olaf and the ball have the same final velocity.
mu = (M + m) v
(0.400 kg) (10.9 m/s) = (70.2 kg + 0.400 kg) v
v = 0.0618 m/s
b) In the second scenario, the ball has a final velocity of 8.10 m/s in the opposite direction.
mu = mv + MV
(0.400 kg) (10.9 m/s) = (0.400 kg) (-8.10 m/s) + (70.2 kg) v
v = 0.108 m/s
