True, the measurement shown is a derived unit.
Let u = the speed of the car at the instant when braking begins.
The braking distance is s = 62.3 m, the acceleration is a = -5.9 m/s², and the braking duration is t = 4.15 s.
Use the formula s = ut + (1/2)at² to obtain
(u m/s)*(4.15 s) + 0.5*(-5.9 m/s²)*(4.5 s)² = (62.3 m)
4.15u = 62.3 + 50.8064 = 113.1064
u = 27.2546 m/s
Let v m/s be the speed with which the car strikes the tree.
Then
v = 27.2546 - 5.9*4.15
= 2.7696 m/s
Answer: 2.77 m/s (nearest hundredth)
Answer:
Slope in Mathematics means the inclination of a line
Answer:
<h2>Force due to biceps is given as</h2><h2>
</h2>
Explanation:
For balancing the force we know that
Torque due to weight hold on his hand = torque due to force applied by biceps
So here we will have
so we have
The gravitational force is inversely proportional to the
square of the distance between their centers. So the
force is greatest when the distance is zero.
