A rock falls from a cliff. 19.6 m is its displacement after 2 seconds
Answer: 19.6 m
<u>Explanation:
</u>
The rock falling from the cliff falls under the effect of gravity. And as it falls, the initial velocity is zero. To calculate the displacement of the rock which fell from the cliff, after 2 seconds, use the equation of motion, as follows,
We know that 2nd equation of motion,
Given that t=2 sec and u=0. Putting the values into the equation, we get,
Answer:
Explanation:
The balance condition, to keep the gate from moving, requires that the net torque be zero, this is, the torques on both sides of the gate must be equal.
- Torque equation: τ = F × d
a) <u>Torque applied by one of the children:</u>
b) <u>Torque applied by the second child</u>:
c) <u>Equilibrium condition</u>:
- τ₁ = τ₂
- 170 N × 0.590m = F × 0.430m
- F = 170 N × 0.590 m / 0.430 m = 233 N ← answer
Answer:
i assume the system is in equilibrium
Explanation:
(W_p-T)(2)+W_b(2.5)= T(sin 45 degrees)(5)
T(((sin 45 degrees)(5)) + 2) = (W_p)(2) + W_b(2.5)= T(5.5355)
Answer:
The time taken is
Explanation:
From the question we are told that
The speed is
The length of the tennis court
Generally the time taken is mathematically represented as
=>
