Question

a student with a mass of 61.0 kg is walking at a leisurely pace of 2.20 m/s. what is the student's kinetic energy (in j)?

Answer 1

147.62J

Step-by-step explanation:

mass(m) = 61.0kg

Velocity(v) = 2.20 m/s

K.E = ?

K.E = ½mv²

K.E = ½ × 61 × 2.2²

K.E = ½ × 61 × 4.84

K.E = 61 × 2.42

K.E = 147.62 J
