Answer:
2.461
Explanation:
Let mass of Bonzo = m1
Mass of Ender =m2
When they push eachother from stationary position
Initial velocity of Bonzo = Vib=0 m/s
Final velocity of Bonzo = Vfb= 1.3 m/s
Initial velocity of Ender = Vie= 0 m/s
Final velocity of Ender = Vfe= -3.1 m/s
We know initial momentum = final momentum
==> m1Vib+m2Vie = m1Vfb+m2Vfe
==> 0+0= m1×1.3 +m2×(-3.1)
==> 1.3m1-3.1m2=0
==> 1.3 m1 = 3.2 m2
==> m1/m2 = 3.2/1.3
==> m1/m2 = 2.461
Answer:
The acceleration of the car will be
Explanation:
We have given that distance from stop sign s = 200 m
Time t = 0.2 sec
We have to find the constant acceleration
Now from second equation of motion
So the acceleration of the car will be
Answer:
chemical - electrical- light
Answer:
47 ms
well the time it takes to fall 100m is the same time it takes to travel 65m horizontally.
The time to fall vertically, t is sqrt(2d/g). [this comes from d = 1/2at^2]
so t = sqrt(2*100/9.8) = 4.52s.
The vertical speed at that time is g*t = 9.8*4.52 = 44.3m/s
The horizontal speed is the horizontal distance over the same 4.52s, = 65/4.52 = 14.4m/s.
so the final velocity is = sqrt(44.3^2 + 14.4^2) = 47.ms
