Answer:
A) 10 m/s
Explanation:
We know that according to conservation of momentum,
m1v1 + m2v2 = m1u1 + m2u2 ..............(equation 1)
where m1 and m2 are masses of two bodies, v1 and v2 are initial velocity before collision and u1 and u2 are final velocities after collision respectively.
From the given data
If truck and car are two bodies
truck : m1 = 2000 Kg v1 = 5 m/s u1 = 0
car : m2 = 1000 kg v2 = 0 u2 = ?
final velocity of truck and initial velocity of car are static because the objects were at rest in the respective time.
substituting the values in equation 1, we get
(2000 x 5) + 0 = 0 + (1000 x u2)
u2 =
x 5
= 10 m/s
Hence after collision, car moves at a velocity of 10 m/s
False.
Force is found by multiplying mass of an object by its acceleration.
F = mass * acceleration
Answer:
Peripheral heart action.
Explanation:
The Peripheral heart action purpose is to keep the blood circulation throughout the body at time of workout.
This is specially proceed through the small central muscles which goes around your heart.
After that it is followed by the peripheral muscles which lies in the arms, legs and in the abs part.
