Answer: 150 miles per hour
Explanation:
600/4 just do 600÷4 on a calculator and you will get 150 miles.
Answer:
14 m/s
18 m/s
22 m/s
Explanation:
The car is moving at constant acceleration, so we can find its velocity at time t using the equation:
where
u = 10 m/s is the initial velocity
is the acceleration
t is the time
Substituting the different times, we find:
At t = 2 s:
At t = 4 s:
At t = 6 s:
Answer:
The answer is below!
Explanation:
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases

The student's vertical speed when he was thrown out = 14.14 m/s
Speed of the student if he hit the ground = 14.14 m/s
Explanation:
Step 1:
It is given that the student reached a maximum height of 10 meters when he was thrown out. The initial speed with which he was throw is to be estimated.
Step 2:
The equation of motion connecting initial velocity, final velocity and distance is where v is the final velocity, u is the velocity with which he was thrown, a is acceleration due to gravity and s is the height.
The final velocity at the highest point 10 meters will be 0
s = 10 m
a = -10 m/
0 = + 2*(-10)*10
u = = 14.14 m/s
Step 3:
The final speed when the student hits the ground will be the same as initial speed of the student when he was thrown out.
So the final speed of the student if he hit the ground would be 14.14 m/s
Step 4:
Answer:
The student's vertical speed when he was thrown out = 14.14 m/s
Speed of the student if he hit the ground = 14.14 m/s
