Answer:
0.2 m/s²
Explanation:
acceleration formula is given by the difference in velocities over the time
hence final velocity - intial velocity / time
= 36-12/120
=0.2m/s²
Answer:
Speed is a scalar quantity, that is, it is a <u>number </u>and indicates how fast (or slow) one travels at any given time.
Velocity is a vector quantity, this means that it<u> has magnitude and direction</u>, that is, how fast an object travels and its where its going (speed + the direction in which the object moves).
Acceleration is the ratio of the velocity change over the time interval in which this velocity change occurred. Acceleration as well as velocity is a vector quantity so it is made up of <u>magnitude and direction</u>.
The differences between these three quantities are important for the description of the movement. In the case of speed and velocity, its difference lies in the fact that velocity indicates the direction in which the movement is taking place (and speed is only a number), which in many physical phenomena the direction of movement is an important property. And the difference between acceleration and velocity is that acceleration instead of a velocity indicates a change in velocity (either in magnitude, direction or both), which tells us how fast a velocity will increase or decrease over time.
Answer:
mass is the amount of "matter" in an object. weight is the force exerted on an object by gravity
Explanation:
Answer:
s = 3.26 m
Explanation:
Given that,
Water leaves at a speed of 8 m/s
We need to find the maximum height that steelhead can jump. Let it can jump to a height of h.
At maximum height, final speed is equal to 0. We can use third equation of motion to find the maximum height.
a = -g
Hence, the maximum height is 3.26 m.
