Without knowing the surface area of the moving object, there is not enough information to answer this question. Rephrase and resubmit.

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?
The force of an object in motion, such as a car traveling at 30 mph, can be calculated using the formula Force = mass x acceleration. Without the mass of the car, we cannot determine the force in newtons.
I'm pretty sure that's going to depend on the vehicle's mass. I'm sitting here performing a gedanken experiment right now, with a house fly and a Mercedes both hitting the same brick wall.

No, the force of impact is not directly proportional to velocity. The force of impact is determined by factors such as the mass of the vehicle and the effectiveness of its brakes in stopping it.
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.
Well, honey, if you're traveling at 60 mph and not wearing a seatbelt, you'll still be traveling at 60 mph when you hit that windshield. Seatbelts aren't magical speed reducers, they just keep you from becoming a human projectile. So buckle up, buttercup, safety first!
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.
