Velocity - math word problems - page 16 of 54
The velocity of an object is the time rate of change of its position. Velocity is a specification of an object's speed and direction of motion (e.g. 20 m/s to the south).In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position) - scalar.

- Radio radius
Two friends have shortwave radios with a range of 13 km. The first of them travels by train at a speed of 48 km per hour along a straight section of track, from which the second of the friends is 5 km away. How long will radio friends be allowed for both - Raindrops
The car runs on a horizontal track at a constant speed of 20 m2-1. It is raining. Raindrops fall in a vertical direction at a speed of 6 m/s. a) How fast is the speed of the drops relative to the car windows? b) What is the angle of the raindro - Otrokovice 60903
From Strážnice, a motor boat left the Baťa canal at a speed of 12 km/h towards the anchorage near Otrokovice. Two hours later, a second boat followed her at a speed of 20 km/h. Both ships arrived in Otrokovice at the same time. How many kilometers is it f - Brian 2
Brian and Jake left their homes 500 miles apart and drove straight toward each other. It took 4 hours for the two to meet if Jake's speed was 15 mph slower than Brian's. What was Brian's speed?
- Kamal
Kamal walks to his school, which is 3 km from his home, in 30 minutes. On reaching, he finds that the school is closed and comes back by bicycle with his friend and reaches home in 20 minutes. His average speed in km/h is - The car
The car travels at a speed of 75 km per hour. If it travels evenly in 3 hours, how many kilometers will it cover? - Car travel How many kilometers did the car travel if it averaged 68 km/h? It started at 8:20 and arrived at its destination at 10:05.
- Temperture drops
In Alaska, the temperature drops a total of -18 degrees over three days. If the temperature drops at a constant rate, what is the change in temperature per day? - Last wagon
A 200 m long train passes through the 700 m long tunnel so that a time of 1 minute elapses from the entry of the locomotive into the tunnel to the exit of the last wagon from the tunnel. Find the speed of the train.
- The tourist
The tourist will cross a 5 km long section in 3 hours. Part of the journey goes at a speed of 0.8 m/s and the other part at a speed of 0.4 m/s. Find the length of the first and second parts of the journey. - The temperature 20
The temperature is rising 4 degrees each hour and is currently 62 degrees. How many hours before the temperature is at least 80 degrees? - Calculating 58401
Suppose the relation s = v applies to the calculation of the path s. t, express the relation for calculating speed v and the relation for calculating time t. Is it true that 10 km will travel at 90 km / h in 10 minutes? - Tandem jump
During the tandem jump, the paratroopers dropped from a height of 1.7 km to a height of 1.5 km above the surface in 4 seconds. At what average speed did they move before the parachute opened? - Tunnel
Kubo sits on a train speeding at 108 km/h. At that moment, the train enters the tunnel, which, according to Kub's book, is 2 km long. Kubo notices that the end of the train has left the tunnel 75 seconds later than the locomotive has entered the tunnel. W
- Acceleration 58021
