It must be noted that during an elastic collision both the momentum and kinetic energy are conserved. For the kinetic energy, it can be solved through the equation,
KE = 0.5mv²
Equating the kinetic energies before and after collision,
0.5(60)(8 m/s)² = (0.5)(60)(x²) + (0.5)(0.45)(35 m/s)²
The value of x from the equation is approximately 7.40 m/s
Answer:
1500 km
Explanation:
600x2.5=1500 (couldn't explain swear filter was for some reason saying I was swearing.) Hope it helps.
Use v^2 - u^2 = 2as
Here, u = 20 m/s , a = -0.5 m/s^2 and v = 0
- 400 = -s ======> s = 400 m
Hope it helps, please mark me as brainliest and give me a good rating. Thank You!
The next step is -748 divide by -11 is 68 m (answer) the pic got cropped sorry
Answer:
B) No.
Explanation:
Okay,so,
this is equation is y=mx +b
mx represents the slope
and b represents the y-intercept
in order to figure this out you need to plot the y-intercept first
that makes its (0,-6) because the 6 is negative in the equation
4x is also equal to 4/1 since we dont know what x is
we have to do rise over run for this
you go up 4 spots on the y intercept from -6 because 4 is positive
then you go to the right 1 time because 1 is positive.
this leaves you at (1,-2)
so, (2,2) is NOT a solution
