Answer:
e) 31.6 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Equation of motion




Time taken by the cars to meet 31.6 seconds.
I'm not sure about the magnitude, but the direction of the normal force is upward.
Answer:
opposite the sun. between the Earth and the sun. rising perpendicular to the sun.
Explanation:
The solution for this problem is:
Let u denote speed.
Equating momentum before and after collision:
= 0.060 * 40 = (1.5 + 0.060) u
= 2.4 = 1.56 u
= 2.4 / 1.56 = 1.56 u / 1.56
= 1.6 m / s is the answer for this question. This is the speed after the collision.
Answer:
second one is correct that is right
