Answer:
V = 6 m/s
Explanation:
Given that,
Initial speed of an object is 20 m/s
Final speed of an object is 10 m/s
Time, t = 5 s
We need to find the average speed of the object during these 5 seconds. Let it is equal to V. Here, time is same. The average speed is given by :
So, the average speed of the object is 6 m/s.
What is the magnitude of the electric field at the dot in the figure? (E=? V/m) What is the direction of the electric field at the dot in the figure? 1. to the left 2. to the right 3. upward 4. downward Thanks!
Answer:
B) Car 2 has both a larger acceleration and a larger average speed.
Explanation:
Car 2 reaches 20 m/s faster than Car 1, so it has a larger acceleration. Car 2 also reaches point B faster than Car 1, so it has the higher average speed.
Answer:
C
Explanation:
Horizontal is constant... if it was on x axis it would be a speed of 0
