1) Magnetic field
2) Electric current
3) Force
Answer:
4.3 * 10 N
Explanation:
To calculate torque, we multiply the distance from the pivot by the perpendicular (the part of the force that acts at right angles to the displacement vector) component of the force to the displacement vector from the pivot.
torque = distance from pivot * perpendicular force
170 Nm= 0.4 m * F
F = 425 N = 4.3 * 10 N rounded off to two significant figures
60mph= 26.8224 m/s
accelerationn= final velocity-initial velocity/time
Work done = force x distance
Work done = 50 x 2
Work done = 100J
