Answer:
it is 2.2 m
Explanation:
because he goes back 2.2 m so 4.4 minus 2.2 equals 2.2
The first thing you should do for this case is to find the horizontal and vertical components of the forces acting on the body.
We have then:
Horizontal = 9-9.2cos (58) = 4.124742769 N.
Vertical = 9.2sin (58) = 7.802042485 N
Then, the resulting net force is:
F = √ ((4.124742769) ^ 2 + (7.802042485) ^ 2) = 8.825268826 N
Then by definition:
F = m * a
Clearing the acceleration:
a = F / m
a = (8.825268826) / (3.0) = 2.941756275 m / s ^ 2
answer:
The magnitude of the body's acceleration is
2.941756275 m / s ^ 2
Answer:
Part a)
P = 8.23 kg m/s
Part b)
v = 3.05 m/s
Explanation:
Part a)
momentum of cart 1 is given as
Momentum of cart 2 is given as
Now total momentum of both carts is given as
Part b)
Since two carts are moving towards each other due to mutual attraction force and there is no external force on two carts so here momentum is always conserved
so here we will have
Potential energy is stored energy meaning you are siting at the the top of the slide doing nothing when you are going down the slide you have both potential and kinetic energy because you are moving but youre not doing anything . Gravity and friction play apart by being gravity and pulling you to the ground and friction with the weight and water togeter going downward.
