Answer:

Explanation:

Samantha walks along a horizontal path in the direction shown the curved path is a semi circle with a radius of 2 m while the horizontal part is for me what is the magnitude of displacement

Displacement is given by the straight line distance between P and Q. Displacement will be length of straight line joining P and Q

a semi circle with a radius of 2 m

Length of this straight line=4+diameter

=4+(2*2)

=8 m

1.) What things signal the coming of spring?
olasank [31]

Answer:

In Explanation

Explanation:

  1. The signs of the coming of spring include firstly the sight of Robins. It is believed that the sight and singing of the Robins is considered arrival of spring by many in the US. Secondly, the winter is not yet over but the blooming of Daffodils first of all flowers is indication of the spring. As the air gets warmer the flowers bud and new leaves start growing on trees since the days also begin to get longer providing much warmth which also an indicator of the spring.
  2. Without the axial tilt of our Earth, firstly, the Sun would have remained above the equator (Equinox) forever but fortunately due to the tilt we get equinoxes twice a year and not forever. Moreover, the temperature and precipitation levels would not vary much and the equator would remain always warm and the poles always cold. Secondly, due to the tilt as the Earth orbits around the Sun and with changes in solstices we get variety of the seasons which would have been impossible otherwise.

A punter wants to kick a football so that the football has a total flight time of 3.7 s and lands 56m away (measured along the g
Irina18 [472]

The maximum height is 16.8 m

Explanation:

In order to find the maximum height reached by the football, we can just analyze its vertical motion.

The vertical motion of the ball is a free  fall motion, affected only by the force of gravity. So it is a uniformly accelerated motion, and we can use suvat equations.

First of all, we notice that the motion of the ball is symmetrical, so the time taken to reach the maximum height is equal to the time needed to fall down: Since the total time of flight is

T = 3.7 s

It means that the time to reach the maximum height is

t=\frac{T}{2}=\frac{3.7}{2}=1.85 s

We can now find the maximum height reached using the equation:

s=vt-\frac{1}{2}at^2

Where:

s is the vertical displacement (the maximum height)

v = 0 is the velocity of the ball at the maximum height

t = 1.85 s is the time

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

Solving for s,

s=-\frac{1}{2}(-9.8)(1.85)^2=16.8 m

What is the average speed of a car that traveled 222.0 miles in 4.596 hours?
Ratling [72]

Answer:

48.3mph

Explanation:

Given that

Distance = 222.0miles

Time = 4.596hours

Average speed = total distance/total time

= 222.0miles/4.596

= 48.3mph

Hence the average speed is 48.3mph
