For each of the motions described below, determine the algebraic sign (+, -, or 0) of the velocity and acceleration of the objec

Wittaler [7]

Answer:

A. Velocity is negative (-)

Acceleration is positive,(+)

B. Velocity is positive. (+)

Acceleration is negative (-)

C. Velocity is zero (0).

Acceleration is negative (-)

Explanation:

The elevator is said to be moving downward, therefore, its motion is in the negative direction as the positive direction is upward in the y-axis. Velocity is negative (-)

As the elevator is making an emergency stop, it is decelerating. Deceleration is negative acceleration. However, since it occurs in the opposite direction, i.e. acceleration vector is pointing upward, acceleration is positive,(+)

The motion of the ball is in the upward direction, therefore the velocity is positive. (+)

The acceleration due to the force of gravity acts in the opposite direction to that of the ball, i.e. downwards, acceleration is negative (-)

At maximum height, the ball will stop moving, therefore, velocity is zero (0).

Since acceleration due to the force of gravity acts downward, the acceleration is negative (-)

Two people of different masses sit on a seesaw. M1, the mass of person 1, is 91 kg, M2 is 45 kg, d1 = 0.8 m, and d2 = 1.1 m. The

mash [69]

Answer:

1/ 485.6 Nm

2/ Clock-wise

3/ 0 and no direction

4/ 1.62 m

Explanation:

1/ Torque is gravity force times the moment arm. Let's g = 9.81m/s2

$T_2 = m_2*g*d_2 = 45*9.81*1.1 = 485.6 Nm$

2/ If person 2 is sitting on the right, the direction of this torque is clock-wise, since the gravity is acting downward.

3/ Assuming that location A is right at the pivot point, then the torque generated by this torque is 0, since the moment arm is 0. This has no direction.

4/ The seasaw is balanced, this means torques generated by 2 people are equal and in opposite direction

$T_1 = T_2$

$m_1gd_1 = m_2g_d_2$

$m_1d_1 = m_2d_2$

$d_2 = \frac{m_1d_1}{m_2} = \frac{91*0.8}{45} = 1.62m$

So the new location for d2 is 1.62m

A dog of mass 10 kg sits on a skateboard of mass 2 kg that is initially traveling south at 2 m/s. The dog jumps off with a veloc

Tasya [4]

Answer:

17 m/s south

Explanation:

$m_1$ = Mass of dog = 10 kg

$m_2$ = Mass of skateboard = 2 kg

v = Combined velocity = 2 m/s

$u_1$ = Velocity of dog = 1 m/s

$u_2$ = Velocity of skateboard

In this system the linear momentum is conserved

$(m_1+m_2)v+m_1u_1+m_2u_2=0\\\Rightarrow u_2=-\dfrac{(m_1+m_2)v+m_1u_1}{m_2}\\\Rightarrow u_2=-\dfrac{(10+2)2+10\times 1}{2}\\\Rightarrow u_2=-17\ m/s$

The velocity of the skateboard will be 17 m/s south as the north is taken as positive
