Answer: a) 2095N
Explanation:
M = w/g = 10100/9.8 = 1.03 x 10^3 kg
Normal force = Gravitational force
Fn = M x g
Friction is
f = m x v^2 / r = 1.03 x 10^3 x (11.5)^2 / 65
F = 2.10 x 10^3 N
N/b to calculate maximum friction force,
Fmax = Us x mg
Fmax = Us x 10100N
It's the one that has a concave line running upward.
Answer:
its should be 2.0 and 4.5 on it
1 m/s
Impulse = Change in momentum
Force × Time = Mass(Final velocity) - Mass(Initial Velocity)
(1.0)(1.0) = (1.0)(Final Velocity) - (1.0)(0)
Final velocity = <u>1 m/s</u>
