Question

could you help with this questionA hockey puck of mass 2000 g is sliding south along the ice and slows at a rate of 0.9 m/s2. What is the net force acting on the puck?Question 8 options:a) 1.8 × 103 N [S]b) 1.9 × 10-1 N [S]c) 1.8 × 100 N [N]d) 1.8 × 102 N [N]

Answer 1

m = mass = 2000 g = 2 kg

a = acceleration = -0.9 m/s^2

F= force

Apply Newton's second Law:

F = m x a

F= 2 kg x -0.9 m/s^2

F= -1.8 N
