The current world-record motorcycle jump is 77.0 m, set by Jason Renie. Assume that he left the take-off ramp at 13.0° to the ho
kotegsom [21]

Answer:

The take-off speed is 41.48 \frac{m}{s}

Explanation:

Given :

Range R = 77 m

Projectile angle \alpha  = 13°

From the formula of range,

  R = \frac{v_{o} ^{2}   }{g} \sin 2\alpha

Find the velocity from above equation,

  v_{o} = \sqrt{\frac{gR}{\sin 2 \alpha } }

  v_{o} = \sqrt{\frac{9.8 \times 77}{\sin 26} }                              ( ∵ g = 9.8 \frac{m}{s^{2} } )

  v_{o} = 41.48 \frac{m}{s}

Therefore, the take-off speed is 41.48 \frac{m}{s}

An object accelerates 3.0 m/s2 when a force of 6.0 N is applied to it. What is the mass of the object?
makvit [3.9K]

Answer:

<h2>2 kg</h2>

Explanation:

The mass of the object can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

From the question we have

m =  \frac{6}{3}  \\

We have the final answer as

<h3>2 kg</h3>

galben [10]

What Newton discovered is that  gravity extends throughout the universe.

<h3>What is gravity?</h3>

The term gravity refers to the force that acts on a body in the universe. It is gravity that makes an object to fall when it is thrown up. The force of gravity acts on every object in the universe and it extends through the universe.

Humans have always known about gravity when they fall from a height and when they threw things up. However, human did not know that gravity extends throughout the universe.

Thus, what Newton discovered is that  gravity extends throughout the universe.
