Question

a cyclist and his bicycle have a combined mass of 88 kg and a combined weight of 862.4 n. the cyclist accelerates at 1.2 m/s². after 2 seconds he reaches a speed of 2.4 m/s. what is his momentum at this point?
a. 105.6 kg·m/s
b. 359.3 kg·m/s
c. 36.7 kg·m/s
d. 211.2 kg·m/s

Explanation:

Step1: Recall the formula for momentum

The formula for momentum \(p\) is \(p = mv\), where \(m\) is mass and \(v\) is velocity.

Step2: Identify the values of \(m\) and \(v\)

Given \(m = 88\space kg\) and \(v=2.4\space m/s\).

Step3: Calculate the momentum

Substitute the values into the formula: \(p=(88)(2.4)\).
