A bus accelerates to 60 m/s to the east in 10 s. What is the buses acceleration? 2. A car traveling at 10.0 m/s to the west acce
professor190 [17]

Answers:

1) a=6\frac{m}{s^{2}}

2) t=8s

Explanation:

1) Acceleration a is defined as the variation of Velocity V in time t :  

a=\frac{V}{t}  (1)

A body also has acceleration when it changes its direction.

In this case we have a bus with a velocity of 60m/s to the east, that accelerates in a time 10s. So, we have to find the bus's acceleration:

a=\frac{60m/s}{10s}  (2)

a=6m/s^{2}  (3)  This is the bus's accelerration

2) Now we have a car that accelerates 2m/s^{2}  to the west in order to reach a speed of 16m/s in the same direction, and we have to find the time t it takes to the car to reach that velocity.

Therefore we have to find  t from (1):

t=\frac{V}{a}  (4)

t=\frac{16m/s}{2m/s^{2}}  (5)

Finally:

t=8s  (6)

A cruise ship travels across a river at 25 meters per minute. If the river is 6200 meters wide, how long
EleoNora [17]

Answer:

248 minutes

Explanation:

6200/25=248

This means there is 248 25s in 6200

which means it will take 248 minutes to travel through the river

Also here's a neat trick:

The units for speed is meters/minute

The units for distance is meters

Dividing distance by speed will cancel out the meters and leave only the speed.
