(50 POINT REWARD) PHYSICS, IMAGE IS ATTACHED BELOW (TRIG/VECTORS)

Physics
1 answer:
daser333 [38]3 years ago
6 0

Answer:

Explanation:

The east vector is 10cos45 = 7.07 km

The north vector is 10sin45 - 10 = -2.93 km

The displacement magnitude is

d = √(7.07² + 2.93²) = 7.65... = 8 km

θ = arctan(-2.93/7.07) = -22.51... = 23° south of east.

On the moon, a feather is dropped from a height of 1.40 m. The acceleration of gravity on the moon is -1.67 m/s2. Determine the
Molodets [167]

Answer:

1.29 s

Explanation:

  • Height = 1.40m
  • Acclⁿ due to gravity = 1.67 m/s²
  • Time of descent = ?

As we know that ,

\sf\longrightarrow Time_{descent}= \sqrt{\dfrac{2H}{g_{(moon)}}}\\\\\sf\longrightarrow t_d = \sqrt{\dfrac{ 2\times 1.4}{1.67}} \\\\\sf\longrightarrow t_d =\sqrt{1.67} s\\\\\sf\longrightarrow \boxed{\red{\sf Time_{descent}= 1.29 s }}

A cat runs and jumps from one roof top to another which is 5 m away and 3 m below. Calculate the minimum horizontal speed with w
icang [17]
ThIs is the same type of problem
find out the time value
3 = 1/2*a*T^2
6/10 = t^2
t = 0.77 seconds
and the distance is given 5 m
thus speed ,= distance/time
speed = 5/0.77
= 6.45 m/s

A level curve on a country road has a radius of 150 m. What is the maximum speed at which this curve can be safely negotiated on
SSSSS [86.1K]

The maximum speed of the car is 24.3 m/s

Explanation:

For a car moving along an unbanked turn, the frictional force provides the centripetal force required to keep the car in circular motion. Therefore, we can write:

\mu mg = m\frac{v^2}{r}

where the term on the left is the frictional force while the term on the right is the centripetal force, and where

\mu=0.40 is the coefficient of friction between the tires and the road

m is the mass of the car

g=9.8 m/s^2 is the acceleration of gravity

v is the speed of the car

r = 150 m is the radius of the curve

Solving for v, we find the (maximum) speed at which the car can move along the turn:

v=\sqrt{\mu gr}=\sqrt{(0.40)(9.8)(150)}=24.3 m/s

For speed larger than this value, the frictional force is no longer enough to keep the car along the turn.
