Answer:
it's acceleration points tangentially to its trajectory in the direction of its motion at the top.
cause only it's horizontal velocity acts at the top. and it will be horizontal in the direction of it's motion.
Do you mean period of time, period as in English spelling, or a period that concerns the medical field?
The formula for solving voltage is V=IR where V represents the voltage, where "I" represent the current and R represents the resistance. Then, the given values are enumerated below and these will help us in solving for the unknown.
V=10 volts
I=?
R=2 ohms
V=IR
I=V/R
I=10/2
I=5 amperes
Therefore, the current is 5 amperes.
Answer:
a = 16 m/s²
Explanation:
Given that,
Initial speed of a roler coaster, v₁ = 6 m/s
Final speed of a roller coaster, v₂ = 70 m/s
Time, t = 4s
We know that, acceleration of an object is equal to the rate of change of velocity. Let the acceleration be a. Its formula is given by :
or
The correct option is (1). Its value is equal to :
Its value is equal to 16 m/s².
