You're driving at 39km/h , when the traffic light 25m away turns yellow. I need to find the constant acceleration required to stop at the light, the stopping time, and weather the acceleration is reasonable. I know how to find the average and instantaneou...

Position vector r⃗ has magnitude of 19.4m and direction angle 235 degrees What are the x and y components? (x,y) Find the components of the vector −2r⃗ and the magnitude of the vector?

Find the components of the vector A⃗ with length a = 1.00 and angle α=10.0∘ with respect to the x axis as shown. I can't display the figure obviously, but I figured 1 x cos(10) and 1 x sin(10) would give the two components I need, but I'm still getting th...

A constant force of 100N , directed upward, is applied to a 5.0kg toy rocket by the rocket's engine. Find the rockets acceleration? I thought it'd be as simple as F=ma to be 20 m/s2 but I was wrong. What am I overlooking?

A constant force of 100N , directed upward, is applied to a 5.0kg toy rocket by the rocket's engine. What is the rocket's acceleration? I used the equation a= F/m to get 20 m/s2 but it was wrong and I don't know where to go from here still?

A ball is traveling down a straight track at 20 m/s. How fast will the ball's speed be after it climbs a hill in the track that is 15 m high?

It starts saying that impulse is related to velocity in a certain way. What is that relationship? I just said impulse = force x time and momentum = mass x velocity So would that be a correct answer to what they're wanting? Also, it says there is a relatio...

A puck with mass m = 0.17kg slides along a frictionless horizontal surface at v = 5.3m/s . It hits and sticks to the free end of a spring with k = 17N/m Find the amplitude and period of the subsequent simple harmonic motion?

A bungee jumper undergoes simple harmonic motion with amplitude 3.5 m and frequency 0.135 Hz. Assume the bungee jumper follows the simple harmonic motion equation x=Acos(wt). A. Determine the bungee jumper's velocity at 0.25 s B. Determine the bungee jump...

A graph of wavelength vs. 1/frequency should be a straight line. What are it's slope and y-intercept? I'm not given any graphs or numbers, just this question. And I know that Velocity = frequency x wavelength And that slope is found by rise/run and m= y2-...

On a roller coaster ride the cart is 250 kg. Initially, the cart is traveling at 5 m/s at the upper level, and then 25 once it reaches the flat lower level that is 8 m off the ground. How high up is the upper level?

I need an expiation on a math concept, because I know the right answer, I just don't know why it is The problem says to find the absolute maximum and minimum of the function f(x)=x^3-12x over the interval [-5, 2] I found the 1st der. 3x^2-12 and set equal...

Solve P=P(base 0)e^kt Solve for t? I have no idea how to solve this

Find the limit as h approaches 0 for ln(1+h)/h

Two thin slits with separation of .0250mm are placed over monochromatic orange laser light at 610.nm. What is the small angle measurement from the central maximum (zero degrees, inline with the source) to the first maximum?

200 m/s2 is still incorrect as well.

Finally was able to solve this myself, but still need help understanding my other question.
