The current world-record motorcycle jump is 77.0 m, set by Jason Renie. Assume that he left the take-off ramp at 11.0° to the ho

rizontal and that the take-off and landing heights are the same. Neglecting air drag, determine his take-off speed.

Answer:

44.9 m/s

Explanation:

Initial velocity = v

Angle at which the projectile is shot at = θ = 11°

g = Acceleration due to gravity = 9.81 m/s²

Range of projectile

R=\frac {v^{2}\sin 2\theta}{g}\\\Rightarrow v=\sqrt{\frac{Rg}{sin 2\theta}}\\\Rightarrow v=\sqrt{\frac{77\times 9.81}{sin (2\times 11)}}=44.9\\\Rightarrow v=44.9\ m/s

The take off speed of Jason Renie's motorcycle was 44.9 m/s

Charged particles posses a region of influence also called a (an)
Delvig [45]

Answer:(c)

Explanation:

Charge particle posses a region of influence called a filed i.e. Electric field.

It is a region around the charged particle such that other charge particle experiences force due to this field. The nature of force is decided by the charge on the particle creating an electric field.

For a positive charge, electric field lines emerge out of it, and for a negative charge, it acts as radially inwards.

A car is traveling at a velocity of 13.5 m/sec (30 mph) north on a straight road. The mass of the car is 1,000 kg. Calculate the
Nat2105 [25]

Answer:

<em> The momentum of the body would be 13500 kg .m/sec</em>

Explanation:

What Momentum Entails

momentum is a property that is possed by all moving objects, it is a product of mass and velocity. A moving object has a magnitude which is the mass of the body and direction which is the  velocity towards a certain direction, so it is a vector quantity

Step by Step Calculation

The momentum of a body can be gotten from the expression below;

p = m x v

where p is the momentum

m is the mass of the body = 1000 kg

v is the velocity = 13.5 m/sec

Given these parameters our momentum would be;

p = 1000 kg x 13.5 m/sec

p = 13500 kg . m/sec

Therefore the momentum of the body would be 13500 kg. m/sec

A +26.3 uC charge qy is repelled by a force
Musya8 [376]

Answer:

+1.46×10¯⁶ C

Explanation:

From the question given above, the following data were obtained:

Charge 1 (q₁) = +26.3 μC = +26.3×10¯⁶ C

Force (F) = 0.615 N

Distance apart (r) = 0.750 m

Electrical constant (K) = 9×10⁹ Nm²/C²

Charge 2 (q₂) =?

The value of the second charge can be obtained as follow:

F = Kq₁q₂ / r²

0.615 = 9×10⁹ × 26.3×10¯⁶ × q₂ / 0.750²

0.615 = 236700 × q₂ / 0.5625

Cross multiply

236700 × q₂ = 0.615 × 0.5625

Divide both side by 236700

q₂ = (0.615 × 0.5625) / 236700

q₂ = +1.46×10¯⁶ C

NOTE: The force between them is repulsive as stated from the question. This means that both charge has the same sign. Since the first charge has a positive sign, the second charge also has a positive sign. Thus, the value of the second charge is +1.46×10¯⁶ C

Two objects of same material are travelling near you. Object A is a 1.9 kg mass traveling 8 m/s; object B is a 2 kg mass traveli
Alex73 [517]

To determine the object which could give the greatest impact we will apply the concept of momentum. The object that has the highest momentum will be the object that will impact the strongest. Our values are

Mass of Object A

m_A=1.9 kg

Velocity of object A

v_A=8ms

Mass of object B

m_B=2 kg

Velocity of object B

v_B=5ms

The general formula for momentum is the product between mass and velocity, then

p = mv

For each object we have then,

p_A=m_Av_A=1.9 kg(8ms)=15.2kg \cdot m/s

p_B=m_Bv_B=2 kg(5ms)=10kg \cdot m/s

Since the momentum of object A is greater than that of object B, then object A will make you feel force upon impact.

If I could lift up to ten tons and I threw a ball the size of an orange but weighed a ton, to the ground, how big of an impact w
Anarel [89]

Answer:

The impact force is 98000 N.

Explanation:

mass = 10 tons

The impact force is the weight of the object.

Weight =mass x gravity

W = 10 x 1000 x 9.8

W = 98000 N

The impact force is 98000 N.
