Answer:
Yep! it's correct might need to double check tho
<span>To find the amount of work done by a force acting on a moving object, we can use this simple equation:
W = F * d * cos(theta)
W is Work
F is the force
d is the distance the object moves
theta is the angle between the force vector and the direction of motion
We know that (F * d) is 190 joules. We can find the work done when the angle is 56°.
W = F * d * cos(theta)
W = (190 J) * cos(56°)
W = 106 J
At an angle of 56°, the work done by the force is 106 joules.</span>
Answer:
B. its consist of waves of varying lengtu
Answer:
b and e
Explanation:
r x F is the formula for torque.
The "turning effect" or torque happens when concentric forces rotate an object along said center.
a) False because T = Fr = Ia (a = angular acceleration)
b) True
c) False. L = Iw (w = angular velocity), which does not equal Ia
d) False. It is torque, not the product of torque and something else
e) True.
The acceleration of the car is 6.86 m/s² and the time taken for the car to stop is 3.64 s.
The given parameters;
- mass of the car, m = 1400 kg
- Initial velocity of the car, u = 25 m/s
- coefficient of kinetic friction, μ = 0.7
The acceleration of the car is calculated as follows;
a = μg
a = 0.7 x 9.8
a = 6.86 m/s²
The time taken for the car to stop is calculated by using Newton's second law of motion;
F = ma
Thus, the acceleration of the car is 6.86 m/s² and the time taken for the car to stop is 3.64 s.
