Answer:
please select me brainly answer
Explanation:
Answer: 14000 N
Given parameters
Initial velocity u = 0
Distance travelled s = 400 m
Time taken t = 20 s
Find out
The force acting on it if its mass is 7 metric tons
Solution
1 metric ton = 1000 kg
7 metric ton = 7 × 1000 = 7000 kg
∴ Mass m = 7000 kg
We know the formula
\(s = ut + \frac{1}{2}at^{2}\)
Substitute the given parameters in the above equation
400 = 0 + ½ a 202
400 = a × 400/2
400 = 200 × a
a = 2 m/s2
Acceleration is equal to 2 m/s2
Force F = Mass m × Acceleration a
Substitute the values of mass and acceleration in the above equation, we get
F = 7000 × 2
F = 14000 N
Answer
The force acting on it if its mass is 7 metric tons is 14000 N
Answer:
Solution
1 metric ton = 1000 kg
7 metric ton = 7 × 1000 = 7000 kg
∴ Mass (m) = 7000 kg
We know the formula
s=ut+12at2
Substitute the given parameters in the above equation
400 = 0 + ½ a (20)2
400 = a × 400/2
400 = 200 × a
a = 2 m/s2
Acceleration is equal to 2 m/s2
Force (F) = Mass (m) × Acceleration (a)
Substitute the values of mass and acceleration in the above equation, we get
F = 7000 × 2
F = 14000 N
Explanation:
The force acting on it if its mass is 7 metric tons is 14000 N.
