Answer:
1.28 m
Explanation:
You are given the initial speed that is 5 m/s. Since the coin is sent upwards, this means that the speed is positive according to the co-ordinate system in the y axis. Additionally, there is the gravity that curbs the coin in the opposite direction making the final speed becomes zero at the highest point, so the gravity takes negative sign.
So, from the explanation we have:
so, we use the following equation to find y (hight)
Answer:
65.625 m/s
Explanation:
c = Speed of light = 3×10⁸ m/s
Relative speed
Relative speed = 35.625 m/s
Velocity of speeder = Velocity of police car + Relative speed
⇒Velocity of speeder = 30 + 35.625 = 65.625 m/s
∴ Velocity of speeder is 65.625 m/s
