Answer:
Yes we can find the initial velocity of car without finding acceleration.
u = 10 m/s.
Explanation:
Given that
s=20 m
Car takes 4 s to come in rest.
We know that when acceleration is constant then we can apply motion equation
----------1
------2
From equation 1 and 2
So we can say that
Given that the velocity of car at final condition will be zero (v=0)
From the above equation we can find the initial velocity of car without finding the acceleration
u = 10 m/s
Answer:
Explanation:
Los átomos que tienen el mismo número de protones y electrones pero diferente número de neutrones se llaman isótopos. Los isótopos de un elemento dado tienen diferentes masas atómicas.
Answer:
Explanation:
mass of the crate = 5 kg
Force on crate = 0.22 N
now the speed of the crate after t = 10 s
Now the time taken by the crate to reach the orchestra pit
now we know that
The graph is showing a constant velocity as the line is horizontal. The initial speed is equal to the final speed as there is no changing in acceleration. The second statement is the correct statement
Initial = 2.5 m/s
Final = 2.5 m/s
