Answer:

4N

Explanation:

a = (7-3)/5 = 0.8m/s^2

F = ma = (5)(0.8) = 4 Newtons

A bicycle has wheels of 0.70 m diameter. The bicyclist accelerates from rest with constant acceleration to 22 km/h in 10.8 s. Wh
Anna11 [10]

Answer:

\alpha=0.16\frac{rad}{s^2}

Explanation:

Angular acceleration is defined as the variation of angular speed with respect to time:

\alpha=\frac{\omega}{t}

The relation between the angular speed and the linear speed is given by:

\omega=\frac{v}{r}

Replacing (2) in (1):

\alpha=\frac{v}{rt}

We need to convert \frac{km}{h} to \frac{m}{s}:

22\frac{km}{h}*\frac{1h}{3600s}*\frac{1000m}{1km}=6.11\frac{m}{s}

Recall that:

r=\frac{d}{2}=\frac{0.7m}{2}=3.5m

Replacing:

\alpha=\frac{6.11\frac{m}{s}}{(3,5m)(10.8s)}\\\alpha=0.16\frac{rad}{s^2}

A car accelerates from rest. It reaches a velocity of 25m/s in 10 seconds. What was the cars acceleration?
mixer [17]

Answer:

We are Given:

initial velocity (u) = 0m/s

final velocity (v) = 25 m/s

time (t) = 10 seconds

acceleration (a)  = a m/s/s

From the first equation of motion, we know that:

v = u + at

solving for a, we get:

a = (v-u) / t

now, plugging the given values in this equation

a = (25 - 0) / 10

a = 25 / 10

a = 2.5 m/s/s

Therefore, the acceleration of the car is 2.5 m/s/s
