We are given with the situation where one is inside a train moving 90 km/h and a baseball is thrown straight up while inside. In this case, the baseball will land in front of you because the person and the ball move as the speed of the train. The choice in your hand doesnt makes sense.

Answer:

here the ball we land exactly into the hand of the person who throw it upwards.

Explanation:

Since train is moving with uniform speed as

v = 90 km/h

now when we throw a ball vertically upwards with certain velocity then due to inertia the ball will automatically start moving in horizontal direction with same speed as that the speed of the train

so while ball is in air then the distance moved by the ball in horizontal direction will be same as that the distance moved by the train in horizontal direction.

So here the ball we land exactly into the hand of the person who throw it upwards.

A 10.0-g bullet moving at 300 m/s is fired into a 1.00-kg block at rest. the bullet emerges (the bullet does not get embedded in
sesenic [268]
Momentum before the hit:
p = mv = 0.01 * 300 + 1 * 0 

Momentum after the hit:
p = 0.01 * 150 + 1 * v

Momentum is conserved:
0.01 * 300 = 0.01 * 150 + v 
3 = 1.5 + v
v = 1.5

The velocity of the block after the collision is 1.5 m/s.

⦁ A car going 50 m/s is brought to rest in a distance of 20.0 m as it strikes a pile of dirt. How large an average force is exer
gtnhenbr [62]

Answer:

the average force exerted by seatbelts on the passenger is 5625 N.

Explanation:

Given;

initial velocity of the car, u = 50 m/s

distance traveled by the car, s = 20 m

final velocity of the after coming to rest, v = 0

mass of the passenger, m = 90 kg

Determine the acceleration of the car as it hit the pile of dirt;

v² = u² + 2as

0 = 50² + (2 x 20)a

0 = 2500 + 40a

40a = -2500

a = -2500/40

a = -62.5 m/s²

The deceleration of the car is 62.5 m/s²

The force exerted on the passenger by the backward action of the car is calculated as follows;

F = ma

F = 90 x 62.5

F = 5625 N

Therefore, the average force exerted by seatbelts on the passenger is 5625 N.
