Explanation:
Crumple zones are sections in cars that are designed to crumple up when the car encounters a collision. Crumple zones minimize the effect of the force in an automobile collision in two ways. By crumpling, the car is less likely to rebound upon impact, thus minimizing the momentum change and the impulse.
Answer:
<h2>2.35 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
force = 0.49 × 4.8 = 2.352
We have the final answer as
<h3>2.35 N</h3>
Hope this helps you
Answer:
E = 58.7 V/m
Explanation:
As we know that flux linked with the coil is given as
here we have
now we have
now the induced EMF is rate of change in magnetic flux
now for induced electric field in the coil is linked with the EMF as
The height of the ball above the ground is 38.45 m
First we will calculate the velocity of the ball when it touch the ground by using first equation of motion
v=u+gt
v=0+9.81×2.8
v=27.468 m/s
now the height of the ground can be calculated by the formula
v=√2gh
27.468=√2×9.81×h
h=38.45 m
A because it’s basic kinetic example
