A 68 kg runner exerts a force of 59 N. What is the acceleration of the runner?
0 m/s2
1.16 m/s2
4012 m/s2
0.87 m/s2

d) ≈ 0.87 m/s²

Hi there !

F = m×a => a = F/m

a = 59N/68kg

1 N = 1kg·m/s²

= (59kg·m/s²)/68kg

= 0.8676 m/s²

≈ 0.87 m/s²

Good luck !

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

in physics zero. in muscle fatigue could be high
