Answer:

I believe that the answer is 3 m/s^2

Explanation:

since acceleration is final velocity minus initial velocity divided by time, we can plug in known values and solve.

a=(f-i)/t

a=(16-4)/4

a=12/4

a=3

3m/s^2 is the acceleration

Shown is a top view of a 50-kg person walking on a large horizontal disk, which rotates with constant angular velocity ω0 = 0.3

JulijaS [17]

We are given
m = 50 kg
ω0 = 0.3 rad/s
v0 = 5 m/s
r = 6 m

We are asked for the horizontal force.
Doing a force balance:
Fc = Fh
mω²r = Fh
Substituting
Fh = 50 kg (0.3 rad/s) (6 m)
Fh = 90 N

Tom Cruise jumped from one building to other building while filming the roof chase scene in Mission: Impossible - Fallout. He di

OLga [1]

Answer:

$v_0=9.9\ m.s^{-1}$

Explanation:

Given:

angle of launch of projectile from horizontal, $\theta=15^{\circ}$

range of projectile, $R=5\ m$

We have formula for the range of projectile:

$R=\frac{v_0^2\times sin\ 2\theta}{g}$

putting the respective values

$5=\frac{v_0^2\times sin\ 30^{\circ}}{9.8}$

$v_0=9.9\ m.s^{-1}$ is the velocity with which Tom should jump to land on the other roof.
