Answer:
32500N
Explanation:
Data obtained from the question include:
m (mass) = 2500 kg
a (acceleration) = 13 m/s2
F (force) =?
Force is the product of mass and acceleration. It is represented mathematically as:
Force = mass x acceleration
F = m x a
With the above formula, the force with which the car strikes the barrier can be obtained as follow:
F = m x a
F = 2500 x 13
F = 32500N
Therefore, the car will strike the barrier with a force of 32500N
Answer:
In 2.748 sec the mailbag reached the ground
Explanation:
We have given height from the ground
At t =2.25 sec helicopter releases a small mailbag so at t = 2.25 sec height from the ground
When the mail box is drooped its initial velocity would zero so u = 0 m/sec
Acceleration due to gravity
According to third law of motion
t = 2.748 sec
