Question

1. - / 1 points a net force of 252 n accelerates a bike and rider at 2.24 m/s². what is the mass of the bike and rider together? kg 15. - / 1 points calculate the speed of a satellite moving in a circular orbit about the earth at a height of 2900×10³ m. the mass of the earth is 5.98×10²⁴ kg and the mass of the satellite is 1400 kg. m/s

Explanation:

Step1: Use Newton's second law

Newton's second law is \(F = ma\), where \(F\) is the net force, \(m\) is the mass, and \(a\) is the acceleration. We need to find \(m\), so we can rewrite the formula as \(m=\frac{F}{a}\).

Step2: Substitute the given values

We are given that \(F = 252\space N\) and \(a=2.24\space m/s^{2}\). Substituting these values into the formula \(m=\frac{F}{a}\), we get \(m=\frac{252}{2.24}\).

Step3: Calculate the mass

\(m=\frac{252}{2.24}=112.5\space kg\)

Answer:

\(112.5\space kg\)
