Answer:
2.136 N-m
Explanation:
From the question,
Applying,
Toque = FL...................... Equation 1
Where F = Force applied to the the ball, L = Length of the forearm
From newton's second law of motion,
F = m(v-u)/t................. Equation 2
Where m = mass of the ball, v = final velocity of the ball, u = initial velocity of the ball, t = time.
Given: m = 0.140 kg, u = 0 m/s (from rest), v = 24 m/s, t = 0.425 s
Substitute into equation 2
F = 0.140(24-0)/0.425
F = 7.91 N.
Also Given: L = 0.270 m
Substitute into equation 1
Torque = 7.91×0.270
Torque = 2.136 N-m
Answer:
Kinetic frictional force will be equal to 56.84 N
Explanation:
We have given mass of the skier m = 58 kg
Acceleration due to gravity
Coefficient of kinetic friction
We have to find the kinetic frictional force
Kinetic frictional force is given by
So kinetic frictional force will be equal to 56.84 N

B. the hydrogens are unbalanced.
D. the chlorines are unbalanced.
That leaves C. to be correctly balanced.
