B.

Areas under the graph:

Cheetah: 0.5*(15+17)(29) = 464
Antelope:0.5*(14+16)(25) = 375

Distance = 100+375-464 = 11m.

thank u

• A sprinter runs a 100 m race in a straight line. He accelerates from the starting block at a constant acceleration of 2.5 m s–2 to reach his maximum speed of 10 m s–1. He maintains this speed until he crosses the finish line. Which time does it take the sprinter to run the race? A 4s B 10s C 12s D 20s. Answer is C, how?

can anyone send me A-Level Physics by Roger Muncaster pdf? I really need one to score good grades I am literally failing physics in every exam I had.

Ans = D
How??

since the magnitude of them are all equal and you require a resultant torque (turning effect) i think D is right as there is upward force and a downward force so no resultant force but since 1 is acting upward from the centre and 1 is from the side they wont cancel the movement as they aint in the same direction so it'll cause a resulatant torque

First of all, make your concepts clear of your theory paper.
Then dive into P5.

At the start, it's gonna freak you out. Be patient.

Solve 4 or 5 or 6 papers with marking scheme, try to understand how to write answers and then discuss your doubts here or on our whats app group or wid your teachers and keep on improving your skills to tackle paper 5.

Good luck folks.

You will learn how to do it by looking at sample papers available online. It's i think solved by one of the XPC members.
