Without knowing the surface area of the moving object, there is not enough information to answer this question. Rephrase and resubmit.
5.71 mph
60/15 = 4The KE of an object is proportional to the square of its speed.Multiplying the speed by 4 increases the KE by (4)2 = 16 .
At 100 mph, an object is traveling about 146.67 feet every second. Therefore, to travel 60 feet at 100 mph would require about 0.41 seconds.

The speed of light is constant. It is 671,000,000 mph.
if a truck weighing 5000 lbs traveling 15 mph hits an object , what is the pressure at impact?
If you were traveling 60 mph and not wearing a seatbelt and collided with a fixed object how fast would you be traveling when you hit the windshield
200 pounds

if an object is moving without any net force or acceleration, it is moving at constant speed, or constant velocity. For example a satellite orbiting the earth is moving at constant speed, a car traveling at 60 mph, a wind of 20 mph. etc.
Equal to.
5.71 mph
Nope. Not to say it cant kill you but it really depends what the object is. Players in baseball get hit with balls all the time at 90-100+ mph. Hockey players lay down on the ice to block shots and have taked slapshots to the face at 90-100 mph. It all depends on what the object is and where it hits you. Take a two by four traveling at 98 mph at your face and you are unlikely to survive.
Speed is a scalar quantity and thus a general term; if a car is traveling at 60 mph that is its speed;Velocity is a vector quantity that has speed and direction associated with it. If a car is traveling at 60 mph due east that is its velocity.The two terms are often used interchangeably.
An object moving at 400 mph is traveling at: 586.7 feet per second.
60/15 = 4The KE of an object is proportional to the square of its speed.Multiplying the speed by 4 increases the KE by (4)2 = 16 .
A train is traveling at 60 mph. If the rate of speed increases 4 mph each hour, how long will it be before the ship is traveling at a rate of 80 mph?
