Answer:
the answer is letter d because both of them are pushing the couch in the same direction so 4 plus 2 will give you 6N
The medicine ball wall hit the ground faster, if that makes sense to you
Answer:
a = -8.912 m/s²
Explanation:
Given,
The initial velocity of the car, u = 28 m/s
The final velocity of the car, v = 0
The distance traveled by car, d = 88 m
The velocity displacement relation is given by the formula
v = d/t
∴ t = d/v
Substituting in the above values in the given equation
t = 88/28
= 3.142 s
The acceleration is given by the formula
a = (v-u)/t
= (0 - 28)/3.142
= -8.912 m/s²
The negative sign is that the car is decelerating.
Hence, acceleration a = -8.912 m/s²
Explanation:
1D motion is motion in only one direction. To put it simply, it's motion along a line. For example, a train on a straight track has 1D motion.
2D motion is motion in two directions. A good example of this is a projectile launched at an angle. It has both vertical motion and horizontal motion.
the answer is (A) the movement of the magnet relative to the coil
