Answer:
5.39 m
Explanation:
From kinematics
where t is time, s is distance and is initial speed in x direction
Now 17.5=17.6634 t
=0.99 s
Using the equation of kinematics
h=5.39 m
Answer:
Explanation:
we know that electric field is given as
from the figure electric field c and electric field a CANCEL OUT EACH OTHER
so, we have E_B and E_D is toward -q direction
a) 0.26 h
b) 71.4 km
Explanation:
a)
In order to solve the problem, we have to know what is the final velocity of the car.
Here, we assume that the final velocity reached by the car is
Therefore, we can find the time taken by the car to reach this velocity by using the suvat equation:
where:
u = 250 km/h is the initial velocity
is the acceleration of the car
v = 300 km/h is the final velocity
t is the time
Solving for t, we find:
b)
In order to find the distance covered by the car, we can use the following suvat equation:
where:
s is the distance covered
u is the initial velocity
a is the acceleration
t is the time
For the car in this problem, we have:
u = 250 km/h
t = 0.26 h (calculated in part a)
Therefore, the distance covered is
Answer:
<h2>750N</h2>
Explanation:
Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.
the expression is Ft=mv
where F= force
m= mass
t= time
v= velocity
Step one:
given data
mass m=3kg
velocity v= 25m/s
time t= 0.10seconds
Step two:
we also know that the force on impulse is given as
Ft=mv
F=3*25/0.10
F=75/0.10
F=750N
<u>The magnitude of the average force on the heavy bag if the duration of the collision is 0.1 is 750N</u>

Answer:
The SI unit for pressure is Pascal (Pa) I believe :)
