A car moves in a straight line at a speed of 52.6 km/h.

Physics
1 answer:
Cerrena [4.2K]3 years ago
6 0

Answer:

32.85 sec.

Explanation:

for the car to travel 0.48km it takes 0.48/52.6 hr. because you see if the car were to move 52.6km in one hr you can write it as 52.6/52.6 hrs or rather 1hr.

we know it takes \frac{0.48}{52.6} hr to travel 0.48km. this is in hours. if we want to convert hours into seconds, we should multiply by 60. and again by 60.

if we multiply by 60 we get the time in minutes( 60 min is 1 hr) and if you multiply that with 60 again we get the answer in seconds.

(0.48/52.6) x 60 x 60 = 32.85 seconds.

4. A 5.00-kg sled starts at rest and accelerates down a 45.0° incline. The coefficient of
Tresset [83]

Answer: 5.64\ m/s^2

Explanation:

Given

mass of sled m=5 kg

Elevation \theta =45^{\circ}

\mu _k=0.185 (coefficient of kinetic friction)

Friction will oppose the motion of the sled while sled weight sin component helps it to move down the incline

W\sin\theta-F_r=ma\\where\\W=weight(mg)\\F_r=Friction(\mu_kmg\cos\theta)\\a=acceleration

Substituting values

mg\sin \theta-\mu_kmgcos\theta=ma\\g\sin \theta-\mu_kg\cos \theta=a\\a=g(\sin 45^{\circ}-0.185\times \cos 45^{\circ})\\a=5.64\ m/s^2

You have 263 mL liquid mercury, What is the mass of mercury that you have
LiRa [457]

Answer:

the mass of a mercury with volume of 263mL = 3559.3 g or 3.56 kg

Explanation:

given:

263 mL liquid mercury

find:

What is the mass of mercury

we know that the density of mercury = 13.5336 g/mL.

now, calculate the mass = volume x density

plugin values into the formula

mass = 263 mL x 13.5336 g/mL.

mass = 3559.3 g or 3.56 kg

therefore,

the mass of a mercury with volume of 263mL = 3559.3 g or 3.56 kg
