I need a picture to help you
Answer:
The acceleration and time are 588 m/s² and 0.071 sec respectively.
Explanation:
Given that,
Speed = 42.0 m/s
Distance = 1.50 m
(a). We need to calculate the acceleration
Using equation of motion


Put the value in the equation


(b). We need to calculate the time
Using equation of motion




Hence, The acceleration and time are 588 m/s² and 0.071 sec respectively.
Answer:
The answer is B 5.0 Volts
Explanation:
I'm using the formula from Ohm's Law like you mentioned for my answer.
V=IR
V=0.050 amps x 100 ohms of resistance
With this you'll have your answer!
Answer:
time=4, answer choice A
time=5.5, answer choice B
Explanation:
This is taken from the kinematic equation, v=vo+(1/2)at^2
Velocity at time 4 = 30+(2.5)(4)^2
Velocity at time 5.5 = 30+(2.5)(5.5)^2
Velocity at time 4 seconds = 70 m/s
Velocity at time 5.5 seconds = 105.63 m/s
