Answer:
The ramp lands at an horizontal distance of 3.989 m
Explanation:
Range: Range is defined as the horizontal distance of a projectile from the point of projection to the point where the projectile hits the projection plane again. It is measure in meters (m)
R = U²sin2∅/g..................................... Equation 1
Where R = The horizontal distance from the end of the ramp, U = rider's speed, ∅ = the ramp's angle to the horizontal.
<em>Given: U = 6.3 m/s, ∅ = 40°, g = 9.8 m/s²</em>
<em>Substituting these values into equation 1</em>
<em>R = [6.3²sin2(40)]/9.8</em>
<em>R = (39.69×sin80)/9.8</em>
<em>R = 39.69×0.985/9.8</em>
R = 3.989 m
Thus the ramp lands at an horizontal distance of 3.989 m
My answer has to be 20 characters but it’s a) air
The statement which best explains why nickel will reach the ground first is: C. The force of air resistance acts more strongly on the sheet of paper than on the nickel.
<h3>What is gravity?</h3>
Gravity can be defined as a force of attraction that controls the movement of objects and the planets such as Earth around the Sun.
<h3>The factors that affect gravity.</h3>
Some of the factors that affect the force of gravitational attraction that is acting on an object or a physical body include the following:
Generally, nickel will reach the ground first before a sheet of paper due to the effect of the force of air resistance because it would act more strongly on the sheet of paper than on the nickel.
