What is the speed of a car that travels 100 meters in 50 sec?
To calculate the speed of the car, you would use the formula speed = distance/time. In this case, the distance is 100 meters and the time is 50 seconds. Plugging these values into the formula, you get speed = 100 meters / 50 seconds = 2 meters per second. Therefore, the speed of the car is 2 meters per second.
A ball is in free fall after being dropped what will the speed of the ball after 2 seconds of free fall?
The speed of an object in free fall increases by 9.8 m/s every second. Therefore, after 2 seconds of free fall, the speed of the ball will be 9.8 m/s * 2 seconds = 19.6 m/s.
A dog that can run 50 m in 5s use the formula for speed to calculate the dogs speed?
50 metres in 5 seconds = 50/5 = 10 metres per second.
What is the speed of the object after falling 2 second?
The object's speed after falling for 2 seconds can be calculated using the formula: speed = acceleration due to gravity (9.81 m/s^2) x time (2 s). Therefore, the speed of the object after falling for 2 seconds would be 19.62 m/s.
A boy runs 400 meters in 50 seconds what is his average speed?
Speed (m/s) = Distance (m) / Time (s)Speed = 400 / 50Average Speed = 8 metres per second
What is the speed of the object during the time interval from 4 seconds to 10 seconds?
2 m/s
A car traveling at 10 m per s exits an off ramp that is 250 m long at what rate must they decelerate to come to a stop?
Initial speed = 10 m/s.Final speed = 0 m/sAverage speed = 1/2 (10 + 0) = 5 m/s.At the average speed of 5 m/s, it will take (250/5) = 50 seconds to stop exactly at the end of the ramp.Deceleration is (change in speed) divided by (time) = -10/50 = -0.2 m/s2
How long does it take a cricket ball moving 50 meters per second to travel 30 meters?
speed = distance/time --> time = distance/speed = (30 m)/(50 m/s) = 0.6 seconds
If Skyler throws the football 50 m in three seconds what is the average speed of the football?
16.7 meters/sec
How hard would you have to push a 50 kg skater to increase her speed by 2 m sec sec?
Any force in the direction she's moving will cause her speed to increase.The more force you use, the faster her speed will increase.If you want to increase her speed by 2 m per sec in one second, then you want heracceleration to be (change in speed)/(time for the change) = 2/1 = 2 m/sec2 .F = M A = (50) (2) = 100 newtonsIf you want to increase her speed by 2 m per sec in 0.1 second, then you want heracceleration to be (change in speed)/(time for the change) = 2/0.1 = 20 m/sec2 .F = M A = (50) (20) = 1,000 newtons.If you want to increase her speed by 2 m per sec in 1 minute, then you want heracceleration to be (change in speed)/(time for the change) = 2/60 .F = M A = (50) (2/60) = 1.667 newtons.
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite?
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite direction in 6 seconds. The speed of the second train is
Hits a speed of 50 m s after 5 seconds what is his rate of acceleration?
If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is50/5 = 10 meters per second2
