Physics predictions? (2 Viewers)

You could definetely say in the question that since the accelerations + velocity didn't math, much of the extra force being exerted were largely from the initial boosting stages + orbit around sun/earth.

So if I said F(capsule)= F(earth orbit) + F(ISS orbit) and this is why is it larger, would that make sense?

That projectile motion question was super easy that should've been q21 IMO
The other one was abt EM induction and it was straightforward, just dump faraday + lenz law -> EM braking
35 was pre straightforward?

Can't really think of a problem which was difficult in the paper but moreso just annoying/wierd. The mark distribution felt really wierd as well

Good to hear that u found it easy

For the rocket question where we had to find the mass of a planet using conservation of energy, do we equate the change in kinetic energy with the change in gravitational potential energy? so 1/2mv^2 = GMm/r

(m= mass of rocket, M= mass of planet)

I did that and it should be right.... cos thats pretty much LOCE
