Answer: Air resistance would be 625Newton

Explanation: For small object the air resistance is directly proportional to the velocity that is if you triple the Velocity the air resistance is also tripled.

But for large object like ball and human the air resistance is proportional to the square of the Velocity that is V². So in this case the velocity given is 90km/h which is also 25 m/s.

So the air resistance on Suzie would be the square of the Velocity which is 25² = 625N

<span>Weight of the skydiver m = 500 N
 Terminal velocity V = 90 km/h
 Here the weight of the person acts as the force, so based on the Newton's third law the applied is the force what we but in the opposite direction making the resistance. So the air resistance exerted on Suzie will be her weight that is 500N</span>

Block A of 5 kg with a speed of 3 m/s collides with block B of 10 kg that is stationary. After the collision, block B travels wi
Lemur [1.5K]

Answer:

-1m/s

Explanation:

We can calculate the speed of block A after collision

According to collision theory:

MaVa+MbVb = MaVa+MbVb (after collision)

Substitute the given values

5(3)+10(0) = 5Va+10(2)

15+0 = 5Va + 20

5Va = 15-20

5Va = -5

Va = -5/5

Va = -1m/s

Hence the velocity of ball A after collision is -1m/s

Note that the velocity of block B is zero before collision since it is stationary

The record for the highest speed achieved in alaboratory for a
Ira Lisetskai [31]

Answer:

0.000234 seconds

Explanation:

Since the row is 0.15m, its radius of rotation must be 0.15 / 2 = 0.075 m

We can start by calculating the angular speed of the rod:

\omega = \frac{v}{r} = \frac{2010}{0.075} = 26800 rad/s

Since one revolution equals to 2π rad. The speed in revolution per second must be

26800 / 2π = 4265 revolution/s

The number of seconds per revolution, or period, is the inverse:

1/4265 = 0.000234 seconds

An eastbound car travels a displacement of 80.0 Km in 45 minutes. What is the velocity
alexgriva [62]

Explanation:

d= 80km = 8000m

t = 45 min = 45/60 h

= 0.75 h

V= ?

we know that,

V = d /t

or,V= 80 km / 0.75 h

  1. or, V= 106.67 km/hr

or,V= 106.67×1000m / 3600 s

2. or, V= 29.63 m/s

If X be a vector 3 X represents  3 added to X  3 times of X  the ratio of X and 3  None
jolli1 [7]

Answer:

The correct option is;

3 times of X

Explanation:

The algebraic properties of a vector are;

Multiplicative identity for real numbers 1

1P = P for each P

Scalar associative property = r(sP) = (rs)P

Scalar distributive property (r + s)P = rP + sP

Vector distributive property r(P + Q) = rP + rQ

Additive inverse of a vector such that a vector P has an inverse -P such that we have;

P + (-P) = 0

Vector associative property (P + Q) + R = P + (Q + R)

Vector commutative property P + Q = Q + P.

6. What is the resultant force on each car below? Remember TWO pieces of
tamaranim1 [39]

Explanation:

In first case, the forces on LHS and on RHS is the same i.e. 3 N. The force acting on the car is balanced force. As a result, the car will not move at all.

In second case,

Force on RHS = 2000 N

Force on LHS = -6000 N

Net force acting on it is given by :

F = 2000+(-6000)

= -4000 N

Hence, this is the required solution.
