Question

3.

Find the kinetic energy of a 20,000-kg truck moving at 110 km/h (leave your answer in standard form​

Answer 1

9,339,136 J

Step-by-step explanation:

Convert km/hr to m/s:

(110km/s)(1000m/km)(1hr/60min)(1min/60s) = 30.56m/s

KE = (1/2)mv^2 = (1/2)(20,000kg)(30.56m/s)^2 = 9,339,136 J
