The air resistance will until it is equal to the and both forces will each other.
The direction of movement to the of the centripetal .
As venus does not any direction of the force .
f = 160 *
f = 56 N
Resultant force = N
0.35 = v – 0 / 1.2
* 1.2 = V
V = ms ^ -1
Speed = ms ^ -1 ( final answer )
Speed possesses only ,whereas possesses magnitude as well as .
300000 = m *
M = / 10
Mass = kg
15000 = * a
a = 30000
Acceleration = ms ^ – 2 ( final answer )
= – 22 –
Velocity change = m s ^ -1 ( final answer )
( Rechecked)
= – 47 /
Acceleration = * 10^ 4 m s ^ -2 ( final answer )
The acting upwards is .
Acceleration = mass
= 600 /
= ms ^ -2 ( final answer )
As the direction of the lorry is ,the velocity is changing,thus the is .
iii) force = acceleration
force = * – 3.6 x 10 ^ 4
force = x 10 ^ 3 N ( final answer ).
The is than the downward the weight.
Resultant force = downwards force
50000 N = thrust – N
thrust = + 400000
thrust = N ( final answer )
= 85 *
Weight = ( final answer )
5.5 * 10 ^ 4 = 85 * * h
55000 = h
/ 850 = h
height difference = m ( final answer )
i) terminal velocity = ms ^ -1
ii) resultant force = upward force
= air resistance –
= {[ 720 ]] – 600
Resultant force = N ( final answer )
The distance is the travelled by car before the are .
The distance is the distance by the car after the brakes are .
Force = acceleration
= 40000 * a
a = 50000 /
acceleration = m s ^ -2 ( final answer )
force = 55000 /
Force = N. ( final answer )
Friction is a produced when objects across each other.It acts in the direction of .
iii) Area the graph would give us the travelled.
f = 800 *
Resultant force = N
Resultant force = Force A – Force B
1200 N = N – Force B
Force B = 5000 N – N
Force B = N ( final answer )
iii) Force B as increases.
The braking because the friction between the and the road .
acceleration = mass
= 600 /
= ms ^ -2 ( final answer )
i) As the train ,the air resistance .This results in resultant force .
ii) When the air resistance ,the resultant force becomes .
Potential energy = gravitational field strength * height
P.E. = 800 * 10 *
Gain in potential energy = J ( final answer )
Pressure with larger .
The force acting in the direction,the is than the downward force,the .
KE = 1 / 2 * ( 5.5 * 10 ^ 4 ) * ( 40 ) ^ 2
= 1 / 2 * ( 5.5 * 10 ^ 4 ) *
Kinetic energy = * 10 ^ 8 J ( final answer )
= 4.4 * 10 ^ 8 / total energy input
total energy input = x 10 ^ 8 / 0.4
energy = * 10 ^ 9 J ( final answer )
iii) 1)
2) .
= final velocity – / time
acceleration = 0 – 20 /
= / 4
= – 5.0 ms ^ -2
deceleration = ms ^ -2
Force = acceleration
= 900 *
Force = N ( final answer )
resultant force = air resistance –
resultant force = – 600
Resultant force = N ( final answer )
acceleration = final velocity – initial velocity time
= 95 – 0 / 0.011
= 95 /
=
average acceleration = * 10 ^ 3 ms ^ -2 ( final answer )
f = * 8636 .36
= N
Average force = N ( final answer )
is a force produced when move across each other,It acts in the direction of .
8000 = m *
m = / 10
mass =
Resultant force =
iii) f = a
a = / m
a = 400 /
acceleration = ms ^ – 2 ( final answer )
Weight = gravitational field strength
W = 1.2 *
Weight = N ( final answer )
The car is moving with .
Resultant force = Force B
1200 N = N – Force B
Force B = 5000 N – N
Force B = N ( final answer )
Force B as speed increases, so the resultant forwards .
acceleration = initial velocity time
1.6 = – u / 5
1.6 * = 20 – u
