Question

Dominic dashes forawrd as quickly as he can. When he reaches a white line, he jumps with a launch velocity of 5.64 m/s at 25.0 degrees.

A) What is Dominic's velocity 0.243 seconds after his jump?

B) How far has Dominic moved horizontally in 0.243 seconds?

C) What is Dominic's velocity 0.486 seconds after his jump?

Expert Solution
Step 1

Given

Initial velocity of dominic = u = 5.64 m/s

At 25° above the horizontal

We have to calculate

A) Dominic's velocity 0.243 seconds after his jump.

B) How far has Dominic moved horizontally in 0.243 seconds?

C) What is Dominic's velocity 0.486 seconds after his jump?
