Answer:
Mass of banana is 
Kg
Explanation:
Step 1: Determine the equation of speed of an object moving in an harmonic motion
Speed of moving in an harmonic motion is given by
Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.
In this question , 
because only at this position maximum speed occurs
So the simplified equation becomes -
OR
Substituting the given values in above equation we get -
Assume spring constant is 
N/m
Mass of banana is Kg
Answer:
Speed of the ball relative to the boys: 25 km/h
Speed of the ball relative to a stationary observer: 35 km/h
Explanation:
The RV is travelling at a velocity of
Here we have taken the direction of motion of the RV as positive direction.
The boy sitting near the driver throws the ball back with speed of 25 km/h, so the velocity of the ball in the reference frame of the RV is
with negative sign since it is travelling in the opposite direction relative to the RV. Therefore, this is the velocity measured by every observer in the reference frame of the RV: so the speed measured by the boys is
v = 25 km/h
Instead, a stationary observer outside the RV measures a velocity of the ball given by the algebraic sum of the two velocities:
v = +60 km/h + (-25 km/h) = +35 km/h
So, he/she measures a speed of 35 km/h.
Answer: it would be daddy
Explanation:
Because I’m daddy
Answer:
Yes because while you slide down the slide you are obviously going to wear clothes and the cotton on your clothes rubbing up against that rubber from the slides, are gonna react by sending a static electricity shock feeling to your body
Explanation:
Answer: 240.25joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
Thus, Workdone = Force x distance
Since, Work = ? (unknown value)
Force = 77.5N
Distance = 3.1metres
Workdone = 77.5 N x 3.1metres
= 240.25 joules
Thus, Amanda did a work of 240.25joules on the crate
