Based on the data collected, explain why a launch angle of 30 degrees (HIGH HORIZONTAL VELOCITY & SMALL TIME OF FLIGHT) will

Gennadij [26K]

Answer:

Explanation:

The horizontal distance traveled by the projectile is given by the formula

$R=\frac{u^{2}Sin2\theta }{g}$

The formula for the time of flight is given by

$T = \frac{2u Sin\theta }{g}$

Case I: when the launch angle is 30°

So, $R_{1}=\frac{u^{2}Sin60 }{g}$

$R_{1}=\frac{0.866u^{2}}{g}$

Horizontal velocity = u Cos 30 = 0.866 u

$T_{1} = \frac{2u Sin30 }{g}=\frac{u}{g}$

Case II: when the launch angle is 60°

$R_{2}=\frac{u^{2}Sin120}{g}$

$R_{2}=\frac{0.866u^{2}}{g}$

Horizontal velocity = u Cos 60 = 0.5 u

$T_{1} = \frac{2u Sin60 }{g}=\frac{1.73 u}{g}$

By observing the case I and case II, we conclude that

R1 = R2

Horizontal velocity 1 > Horizontal velocity 2

T1 < T2

A car with a mass 1200 kg accelerates at 1.89 m/s2. What is the total force exerted by the car on the road (answer in N to two d

Reptile [31]

Formula:
F = ma
F: force (N) m: mass (kg) a: acceleration (m/s^2)

Solution:
F = ma
F = 1200 × 1.89
= 2268N

A solar cell that transforms 300 J of light energy into 45 J of electrical energy and 255 J of wasted energy. whats the efficien

Setler [38]

Answer:

15%

Explanation:

Step one:

Given data

Energy source= 300J

Useful energy = 45J

Waste energy = 255J

Required

The efficiency of the solar system

Step two:

The efficiency is computed by factoring only the useful work and the energy source

Efficiency= 45/300*100

Efficiency= 0.15*100

Efficiency= 15%
