Question

A student was taking a rock-climbing class that used an indoor climbing wall. before he started, the instructoe asked for his weight. if the student had a mass of 88.6kg. what was his weight ?

Answer 1

Weight is the force of gravity acting on a body. By newton's second law, that force can be calculated as W=mg, where g is the acceleration of gravity, 9.81 m/s^2. So, for the intrepid climber, this would be approximately 88.6 x 10 Newtons or about 886 Newtons.
