What is the mass of a 4900 Newtons bobsled?

To calculate the mass of the bobsled, you would use the formula F = m * a, where F is the force applied (4900 N), m is the mass of the bobsled, and a is the acceleration (usually taken as g, acceleration due to gravity, approx. 9.81 m/s^2). Rearranging the formula to solve for mass, you would have m = F / a = 4900 N / 9.81 m/s^2 ≈ 499.5 kg.


A rock weighing 98 newtons is pushed off the edge of a bridge 50 meters above the ground What was the potential energy of the rock before it began to fall?

The potential energy of the rock before it fell can be calculated using the formula PE = mgh, where m is the mass of the rock, g is acceleration due to gravity (9.8 m/s^2), and h is the height. To calculate the potential energy, we need the mass of the rock, not just its weight in newtons. Given the weight of the rock is 98 N, we would need the mass of the rock to calculate its potential energy.


What is the mass of 100 N?

100 N is a force. An object of mass about 10.2Kg would experience a gravitational force of 100N.


What is the mass of person who weighs 400 N?

The mass of a person who weighs 400 N can be calculated using the formula: weight = mass * gravity, where gravity is approximately 9.8 m/s^2. Therefore, mass = weight / gravity, which gives a mass of about 40.8 kg for a person who weighs 400 N.
