Once a ball leaves a table at 10 m/s, how long will it take to hit the floor
Zarrin [17]

<u>Answer:</u>

The time taken for the ball to hit the floor as 1.02 seconds

<u>Explanation:</u>

As per the given question, the ball leaves at a speed from the table with an initial velocity of 10 m/s, we have the equation

\mathrm{V}_{\mathrm{f}}=\mathrm{V}_{\mathrm{i}}+\mathrm{at}

where Vf represents the final velocity

 Vi represents the initial velocity  

a represents the acceleration and

t represents the time

\mathrm{V}_{\mathrm{f}}=\mathrm{V}_{\mathrm{i}}+\mathrm{at} after rearranging

 \mathrm{t}=\frac{\mathrm{vf}-\mathrm{vi}}{a}

  \mathrm{t}=\frac{0-10}{9.8}  = 1.022 seconds

How far (in feet) could a pitcher throw a baseball on flat, level ground if he can throw it at 100mph? (Neglect wind drag and th
ehidna [41]

Answer:

R = 668.19 ft  

Explanation:

given,

speed of the ball thrown by the pitcher = 100 mph

to travel maximum distance θ = 45°

distance traveled by the ball = ?

using formula

1 mph = 0.44704 m/s

100 mph = 44.704 m/s

R = \dfrac{u^2sin2\theta}{g}

R = \dfrac{44.704^2sin2\times 45}{9.81}

R = 203.71 m

1 m  = 3.28 ft

R = 203.71 × 3.28

R = 668.19 ft  

hence, ball will go at a distance of 668.19 ft   when pitcher throw it at 100 mph.

A particle is located on the x axis 4.9 m from the origin. A force of 38 N, directed 30° above the x axis in the x-y plane, acts
Juli2301 [7.4K]

Answer:

Torque is 93 Nm anticlockwise.

Explanation:

We have value of torque is cross product of position vector and force vector.

A force of 38 N, directed 30° above the x axis in the x-y plane.

        Force, F = 38 cos 30 i + 38 sin 30 j = 32.91 i + 19 j

A particle is located on the x axis 4.9 m and we have to find torque about the origin on the particle.

Position vector, r = 4.9 i

Torque, T = r x F = 4.9 i x (32.91 i + 19 j) = 4.9 x 19 k = 93.1 k Nm

So Torque is 93 Nm anticlockwise.
