∙ 14y agoA car of mass 1200 kg is being towed horizontally on the end of a horizontal cable the car accelerates uniformly from rest to a speed of 15ms-1 in a distance of 75m show that the accleration of t?
Motion formulas
vfinal = vinitial + acceleration * time
vf = vi + a * t
vf - vi = a * t
t = (vf - vi ) ÷ a
average velocity = (vi + vf) ÷ 2
distance = average velocity * time
d = (vi + vf) ÷ 2t
t = 2d ÷ (vi + vf)
Set the 2 equations equal to t, equal to each other.
(vf - vi ) ÷ a = 2d ÷ (vi + vf)
This would look better as a proportion, but wiki doesn't copy symbols!
Cross multiply and divide
(vf - vi ) * (vi + vf) = 2*a*d
vf2 - vi2 = 2*a*d
vf2 = vi2 +2*a*d
Your question:
Mass = 1200Kg
Distance = 75m
vi = 0 m/s
change in velocity = (vf - vi) = 15m/s - 0 /s = 15m/s
(vf - vi) = 15m/s
vf2 = vi2 + 2*a*d
vi2 = 0
vf2 = 2*a*d
152 = 2*a*75 a = 1.5 m/s
vf = vi + at
t = (vf - vi)÷ a
t = 15m/s ÷ 1.5 m/s2 = 10 seconds
Force = mass * acceleration F = 1200kg * 1.5 m/s2 =
F = 1800 Newtons

∙ 14y agoA mass accelerates uniformly when a constant force is applied to it, resulting in a constant rate of change in velocity over time. This occurs in scenarios where there is no opposing force or acceleration due to factors such as friction, air resistance, or gravity.

4/3 ms-2.
an object uniformly accerlerates over a distance of 100 m in 20 seconds. calculate the acceleration.
160 m
So it's acceleration is 4m/s2. So at any point because it says uniformly, it will be accelerating at 4m/s2 each second
Motion implies momentum, which implies velocity. Linear implies a straight line. Accelerating implies changing velocity. And uniform implies constancy. So, when an object moves in a straight line and accelerates at a constant rate, you have uniformly accelerating linear motion.
Yes, projectile motion is an example of uniformly accelerated motion in two dimensions. This is because the acceleration due to gravity acts vertically downwards throughout the motion, causing the object to accelerate at a constant rate in the vertical direction while moving horizontally at a constant velocity.
The isotropicantenna by definition has a radiation pattern that is a perfect sphere. The omni driectional antenna is characterized by a radiation pattern resembling a doughnut.

It would be worksheet, which would be contained in a workbook.
Acceleration cannot be measured in metres per second. There is, therefore a fundamental problem with the question.
