Answer:
It's is c coz the weight is equal to the normal force
70 meters is your answer
Note that the beginning is the 30 meter mark, and the ending is the 100 meter mark. Subtract the beginning amount from the end:
100 - 30 = 70
The vehicle traveled 70 meters.

B.Warmer air molecules move faster and get farther apart. As they get farther apart, they become less dense and rise.
The correct answer is letter A. red. Young red stars would most likely be found in a giant molecular cloud. Red stars<span> are cooler than the sun, with surface temperatures of 3,500 K for a bright red star</span>
Answer: x= 4.761 m/s
t=0.786 sec
Explanation: In a projectile motion (or 2D motion), the object is launched with an initial angle and an initial velocity
The components of the velocity are
<em>The magnitude, which is the speed, and the direction in which the motion is happening.</em>
Similarly the displacement has the components
The last formula is valid only if the object is launched at ground level, as our frog does.
There are two times where the value of y is zero, when t=0 (at launching time) and when it lands back from the air. We need to find that time t by making y=0
Dividing by t (assuming t different from zero)
Then we find the total flight as
Replacing this time in the formula of x
We can solve for
Knowing that x=2.20 m and °
We now compute t
