i think that it is 50 because if u multiply you will get 50.
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Substituting the values: acceleration = (5 m/s - 15 m/s) / 2 s = -5 m/s^2. Therefore, the acceleration of the car is -5 m/s^2, indicating that it is decelerating.
To calculate the braking force, we need to determine the deceleration first. Using the formula: final velocity = initial velocity + (acceleration * time), we find that the deceleration is 2.5 m/s^2. Then, using the formula: force = mass * acceleration, we get a braking force of 200 N.
The momentum of an object is calculated as the product of its mass and velocity. So, the momentum of a 3kg object moving at 5m/s would be 15 kg*m/s.
F = ma. Thus, acceleration is the force divided by the mass. Here, 10/2 = 5ms-2.
The principle of conservation of momentum explains this result. The total momentum of the system before the collision is equal to the total momentum after the collision. In this case, the momentum gained by the 5kg cart moving at 10 m/s is equal to the momentum lost by the 10kg cart, resulting in a balanced conservation of momentum.

4m/s Acceleration = velocity change / time = (9m/s - 5m/s) / 4 sec A = (9-5) / 4 = 1 m/s2.
66.7 m/s2
The momentum of an object is calculated as the product of its mass and velocity. So, the momentum of a 3kg object moving at 5m/s would be 15 kg*m/s.
Force=mass*acceleration -> (70 kg)*(5m/s^2)=350 kg m/s^2 OR 350 N (newtons)
Mission
While typing there is no provision to raise -2 as the power of s ie s-2 So it has been just typed as ms-2. m s-2 read as metre per second sqare. This is the unit for acceleration. So 5 ms-2 is the acceleration on a moving body.
Use Pythagoras' Theorem to find its value. For example, if it was moving at 3ms-1 in the x direction and 4ms-1 in the y direction, its absolute velocity would be the square root of (9+16), 5ms-1.
F = ma. Thus, acceleration is the force divided by the mass. Here, 10/2 = 5ms-2.
2ms lower faster
