m / s ( final answer )
Uniform is that there is change in per .
(i) (a =) / delta t
= 25 /
= m / s^2 (final answer)
(d =) speed x .
= 1 / 2 ( 5 + 8 )
=
( b) (a =) V – U /
= / 4 – 2
= -5 /
= m / s ^2 (final answer)
( i ) (P.E =) mg
= 30 x x 1.6
Decrease in = J ( final answer )
Equal or regular in speed in the
Constant gradient on the graph.
passed on by colliding ( with)
( i ) s
( ii ) s
( iii ) s ( final answer )
Hot or water
Area of triangle
= 1 / 2 x height
= 1 / 2 x x 7.3
= (375) m (125) m ( final answer )
A specific capacity is the amount of that is required to change the of mass by degree centigrade.
It takes a lot of to change the of a body of water,therefore it will take to .
at the start to energy at end.
(Q =) mc {[delta T] [change in temperature]
= m (4200)(34)
m=72000 (4200) (34)
m = ( final answer )
( i )
(ii) s = /
7 = d /
Thinking distance = m
( iii ) 1 / 2 x (difference) x
( final answer)
(Q =) mc
= ( 4200 ) ( 54 )
=
Loss of thermal energy = ( final answer )
No .
( i ) (Pressure) = / Area
F = x A
F = 1.2 x 10 ^ 6 x ^ -5
F =
( ii ) Area , increase
= 50 x
distance = ( final answer )
placed
S = t
(Velocity) is the change in upon .
V = / t
(a =) V – U /
= / 5
= – 45 /
=
average deceleration =
Negative means or decrease in .
Both are in the direction.
(F =) a
= (9)
F = ( final answer )
a = / delta t
1.8 = delta V /
Speed = m/s ( final answer )
a=
(a =) V – U /
= 0- 20 / 4
= / 4
= m / s ^2
deceleration = ( final answer )
-> 100
1 box ->
/ 5 = 20
= 3 x
= m ( final answer ).
The value of is the as .
F = a
F = ( 5 )
force = ( final answer )
5 boxes – >

10 /
6 x = s ( final answer )
s
S = / t
= 500 /
=
(PE =) g
20,000 – = 5000
= mgh
5000 = ( 10 ) h
5000 500 = h
h= m ( final answer )
