Jaylen is a championship runner of the school's track team. during one of his trials, his speed was measured at 15.1 m/s. find jaylen's kinetic energy during that trial if his mass is 54.6 kg.

Kinetic energy of any moving object = (1/2) (mass) (speed)²

Jaylen's KE = (1/2) (54.6 kg) (15.1 m/s)²

KE = (27.3 kg) (228.01 m²/s²)

KE = 6,224.7 kg-m²/s²

KE = 6,224.7 Joules

That may sound like a lot of KE.  But Jaylen's speed of 15.1 m/s is almost 50% faster than Usain Bolt's average speed for his world's record in the 100 meters, so you'd naturally expect amazingness from Jaylen.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
