BOLT VS DINOSAUR

A university professor in America found an interesting way to engage his psychics students- by asking them if famous runner Usain Bolt is faster than a dinosaur!

Scott Lee, from the University of Toledo, asked his students to work out if one of the world's greatest ever sprinters could beat Dilophosaurus wetherilli in a 100m race.

The students looked at velocity (how fast you are moving in a certain direction) and acceleration (how your velocity changes over time). They also had to consider Newton's second law of motion, which explains that the greater the mass (the proper scientific term for what we might usually call weight) of an object, the more force it will take to accelerate it.

As Usain Bolt's mass is much less that Dilophosaurus, Bolt has an advantage. It takes a lot less force for him to push off at the start of the race and build up speed over the 100m distance.

The second law of motion and Bolt's ability to accelerate proved to be the winning formula. The students calculated that Bolt would leave Dilophosaurus in the dust, beating it by 2 seconds!

Comic Relief challenge

By Cressie

For Comic Relief, Tom Daley took on an epic challenge to get from London to his home town of Plymouth by rowing, swimming, cycling and running.

Cressie getting Tom's autograph

I was lucky enough to welcome him, along with my parents and my brother Ned, to Bovey Castle, where he finished the third leg, cycling 130 miles (209km) from Southampton to Dartmoor. I was so excited to see him because I knew how incredible his diving was.

Once he had settled in, we were lucky enough to get his autograph. We saw him off on the last leg of his immense journey, which took him from Bovey Castle to Plymouth, a total of 30 miles (48km) of running.

He said that in training he had only ever run 18 miles (29km) before, so this would be huge! This was an experience I'll never forget!
