A man and a woman exert a total of 900 N by pushing a car 20 meters across the street The man exerts twice as much force as the woman How much work does the man do

The man exerts a force of 600 N and the woman exerts a force of 300 N. Work done by the man = Force x displacement = 600 x 20 = 12,000 J Hence, the man performs 12,000 joules of work.

The value of the impulse equals the force x the

The value of the impulse equals the the force times the time.

The tangent of an angle equals the ratio of the

Sine of the angle to its cosine.
