Speed equation using mass

WebTo determine the acceleration of the car, use the equation a = v 2 / R. The solution is as follows: a = v 2 / R a = (10.0 m/s) 2 / (25.0 m) a = (100 m 2 /s 2) / (25.0 m) a = 4 m/s2 To determine the net force acting upon the car, use the equation F net = m•a. The solution is as follows. F net = m • a F net = (900 kg) • (4 m/s 2) Fnet = 3600 N WebThe equation for the magnitude of torque is τ = r F sin θ, where r is the magnitude of the lever arm, F is the magnitude of the linear force, and θ is the angle between the lever arm and the force. The lever arm is the vector from the point of rotation (pivot point or fulcrum) to the location where force is applied.
