@little dove what part do u need help w

split latch
#

p=mv

#

if the momentum is the same

#

then make mv= initial momentum

#

78x5.6= (78+6)v

#

and rearrange for v

#

for a do

#

suvat

#

s=u + at^2

#

wiat wrong equatioj

#

v^2=u^2+2as

#

so square root

#

2(9.8)(1.6)

#

it is an a level question my bad

#

but you can probably do a and part of b

#

I don’t know about c and d

royal garden
#

part c i think shld be

v = u + at
0 = 5.2 + 0.06a
-5.2/0.06 = a = -86.666 ms-2

F - 84g = 84a
F - 823.2 = 7280
F = 7280 + 823.2 = 8103.2N
