The acceleration a is correct.TyErd said:um to find acceleration can't you use a=gsinθ, but if you use that its 10xsin(5.740) which equaks 1.001 because if sinθ=10/100 then θ=5.74. However if I use your equation i get a=4.5m/s/s
In the problem they have askedTyErd said:how do i calculate af?
This step is wrong.TyErd said:so is af = 4.500 - 1.001?, then the braking force is 1000*3.499=3499?
mg*sinθ ...> Force acting on the sledge due to gravity in the downward directionTyErd said:whats the difference between a and gsinθ?
Acceleration is the rate of change of an object's velocity over time. It measures how quickly the object is speeding up, slowing down, or changing direction.
Acceleration can be calculated by dividing the change in an object's velocity by the change in time. The formula for acceleration is a = (vf - vi)/t, where vf is the final velocity, vi is the initial velocity, and t is the change in time.
Acceleration is typically measured in units of meters per second squared (m/s²). However, other common units include feet per second squared (ft/s²) and kilometers per hour squared (km/h²).
Positive acceleration occurs when an object's velocity is increasing, while negative acceleration (also known as deceleration) occurs when an object's velocity is decreasing. In both cases, the object is experiencing a change in its velocity.
Acceleration can cause an object to speed up, slow down, or change direction. It is an important factor in determining an object's overall motion and can be influenced by various forces, such as gravity or friction.
