hey, i have a lab due for a grade 10 physics class tomorrow. I am not too smart with this stuff, and I'm stuck with this question. can someone please help me out;
Question: how long would it take a cart on a similar ramp to reach a velocity of 90km/h?
i did a lab where we measured the speeds of a cart going down a ramp with a ticker tape timer thing.
i calculated that the average velocity was 166cm/s [down]
... there's one more question too;
calculate the velocity the cart would have if it was allowed to run down a similar ramp for a period of 5.0s
im sure this is real basic stuff, I am just stuck
my data was
time 0.0 velocity (cm/s) 0
time 0.05 velocity 16
time 0.15 velocity 31
time 0.25 velocity 47
time 0.35 velocity 63
time 0.45 velocity 72
time 0.55 velocity 99
time o.65 velocity 107
time 0.75 velocity 123
time 0.85 velocity 183
time 0.95 velocity 154
its basically uniform when plotted on a velocity vs time graph
