Answer:
Explanation: The time taken by the object to reach the ground depends up on the vertical velocity of the object.
The object horizontal velocity component only moves the object in forward direction and does not have any effect vertically
as the object is launched horizontally its initial vertical velocity is zero
the object experiences downward fall due to gravitational acceleration only since there is no air resistance
therefore a=g
the distance covered =s=h
now the kinematic equation could be used
You are correct because nothing is being done to the cake
Answer:
18.24 seconds
Explanation:
First you convert the km/h to m/s, 70km/h=(175/9)m/s,85km/h=(425/18)m/s.
You know it took 10 seconds for the police to reach 85 km/h. Calculate the distance that the car is ahead of the police (175/9)*10=1750/9m. Then by divide 1750/9 with 425/18, you will get the value 8.24. Add the 10 seconds with the 8.24 you will get 18.24 sec which is the total time.
Answer:
A larger impulse. A 1-kg ball has twice as much speed as a 10-kg ball.
Explanation:
Answer:
Explanation:
Since,
<h3><u>1 kWh = 1 unit</u></h3>
So,
1.6 kWh = 1.6 units
If,
<h3>1 unit = 9p</h3>
1.6 units = 9p × 1.6
1.6 units = 14.4p
