Answer:
measure the position every so often with a stopwatch
Explanation:
A possible method of measurement is to place a measuring tape along the path and measure the position every so often with a stopwatch, with this we can make a graph of position against time and by extrapolation find the initial velocity.
This is a method used in measurements of uniform movements of bodies
Answer:
The correct answer is The plates smash together with no subduction. I just took this on Edge. Glad I could help!
By conservation of momentum,
Distance lighter fragment slide= 7*6.7=46.9m
Answer:
velocity = distance / time taken
= 200/4
= 50 m/s
is the correct answer
Answer:
T=189.15 N
Explanation:
As we know that for downward motion
F acting = F (weight) - Tension T
m a = mg - T
⇒ T = m (g - a)
T = 29.1 kg ( 9.8 m/s² - 3.3 m/s²)
T=189.15 N
