A car accelerates at a constant rate from 0 to 50 mph in three fourths min. How far does the car travel during that​ time?

Physics
1 answer:
Helen [10]3 years ago
8 0

Answer:

the car have travelled 0.31 mile during that​ time

Explanation:

Applying the Equation of motion;

s = 0.5(u+v)t

Where;

s = distance travelled

u = initial speed = 0 mph

v = Final speed = 50 mph

t = time taken = 3/4 min = 3/4 ÷ 60 hours = 1/80 hour

Substituting the given values into the equation;

s = 0.5(0+50)×(1/80)

s = 0.3125 miles

s ~= 0.31 mile

the car have travelled 0.31 mile during that​ time

A 4kg watermelon is dropped from a height of 45m. What is the velocity of the watermelon just before it hits the ground?
Makovka662 [10]

Answer:

v=30 m/s

Explanation:

h - height

g - acceleration due to gravity=10

t - time

v- velocity

h =  \frac{1}{2}  \times g \times t {}^{2}

45 = 5t²

t² = 9

t=3 seconds

v=g×t

v=10×3

v=30 m/s

A proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton. Dete
gavmur [86]

Answer:

Electric field, E=10^{-7}\ N/C

Explanation:

It is given that, a proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton such that,

qE=mg

E=\dfrac{mg}{q}

E=\dfrac{1.67\times 10^{-27}\times 9.8}{1.6\times 10^{-19}}

E=1.02\times 10^{-7}\ N/C

or

E=10^{-7}\ N/C

So, the magnitude of electric field at the location of the proton is 10^{-7}\ N/C. Hence, this is the required solution.

The inclined plane in the figure above has two sections of equal length and different roughness. The dashed line shows where sec
saveliy_v [14]

The static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta.

The given parameters;

  • <em>mass of the block, = M</em>
  • <em>coefficient of static friction in section 1, = </em>\mu_s_1<em />
  • <em>angle of inclination of the plane, = θ</em>

<em />

The normal force on the block is calculated as follows;

Fₙ = Mgcosθ

The static friction exerted on the block by the incline is calculated as follows;

F_s = \mu_s F_n\\\\F_s = \mu _s_1(Mg cos\ \theta)\\\\F_s = \mu _s_1 Mgcos\ \theta

Thus, the static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta
