Ed drove to New Jersey at 30mph. He drove back home in 3 hours at 50 mph. How many hours did it take Ed to drive to New Jersey? - Book reading
If we read the book at a speed of 15 pages a day, we read it three days before we read it at a speed of 10 pages per day. If I read six pages per day, how many days will I read the book? - Skid friction
Find the smallest coefficient of skid friction between the car tires and the road so that the car can drive at a 200 m radius at 108 km/h and does not skid. - Average speed
When the bus stops at a bus stop driving average speed is 45 km/h. If it did not stop, it would drive at 54 km/h. How many minutes of every hour does it spend at stops? - The projectile
The projectile was fired horizontally from a height of h = 25 meters above the ground at a speed of v0 = 250 m/s. Find the range and flight time of the projectile. - 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. - Tractor vs car
Behind the tractor, which was traveling at an average speed of 20 km/h, a car started in two hours and overtook it in 1 hour. At what speed was the car moving? - Raindrops
The train runs at a speed of 14 m/s, and raindrops draw lines on the windows, which form an angle of 60 degrees with the horizontal. What speed do drops fall? - Positional energy
What velocity in km/h must a body weighing 60 kg have for its kinetic energy to be the same as its positional energy at the height of 50 m? - Potential 12431
From what height does a hammer weighing 200 kg fall if its initial potential gravity was 6 kJ? - Acceleration 7149
The body went through a uniformly accelerated path of 30 m in 10 seconds while its speed increased five times. Find the initial speed and acceleration. - 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? - Speedboat 3189
At 12:15, a train speeding 55km / h left the station. Twelve minutes later, an 80km / h speedboat set off behind the train. What time does the express train catch up? How far from the station? - The stadion
John can run around a circular track in 20 seconds and Eddie in 30 seconds. Two seconds after Eddie starts, John starts from the same place in the opposite direction. When will they meet? - Up and down motion
We throw the body from a height h = 5 m above the Earth vertically upwards v0 = 10 m/s. How long before we let the second body fall freely from the same height to hit the Earth simultaneously?
