Answer:
a. 3,392.7 N
b. 3,392.7 N
Explanation:
We are given the following information;
- Mass of the truck as 1052 kg
- initial speed as 0 m/s
- Final speed as 20.0 m/s
- Time taken as 6.20 s
#a. We are required to calculate the acceleration;
We need to know the formula of getting acceleration;
a = (v-u)/t
Where v is the final velocity, u is the initial velocity
Therefore;
a = (20 m/s - 0 m/s)/6.20s
= 3.225 m/s²
Thus, the average acceleration of the truck is 3.225 m/s²
#b. We are required to calculate the net force on the truck
We need to know that;
According to the second Newton's law of motion, F=ma
Where F is the net force, m is the mass and a is the acceleration.
Therefore;
Net force, F = mass × Acceleration
= 1052 kg × 3.225 m/s²
= 3,392.7 N
Thus, the net force on the truck is 3,392.7 N
Wavelength*frequency=velocity
(331m/s)/(.6m)
Frequency = 551.666 1/s
It'll speed up in the direction it's being pushed unbalanced. Or, it could slow down if applied the right amount of unbalanced power. And finally if the unbalanced push is pushed it could change the direction of it's current motion it was traveling.<span>
